Graf, who retired in 1999 and married Andre Agassi two years later, said her life has moved on so much that she is unconcerned whether her records are matched or broken.

It’s a statement which offers a different perspective as Serena Williams continues her long and difficult quest to equal the all-time record for Grand Slam singles titles.

No singles player, man or woman, has won all four majors in the same year since Graf, whose Open-era record of 22 Slam titles was finally surpassed by Williams last year.

    “Those are great memories and treasured times,” the 49-year-old told AFP at the WTA Elite Trophy in Zhuhai, for which she is a global ambassador.

She added: “I rarely look back, but when I do, it’s moments that for sure are going to be with me all my life. But I’m not one to worry to much about records — I never have done.

“I’ve been really fortunate to have had the career that I had, and to give it all, and to retire and start my next chapter of life. I feel it’s not something that has that kind of priority or importance any more in my life.

“I’m not too worried if my record stands for a long time or not.”

Williams returned to the circuit this year after having a baby, and twice came close to matching Margaret Court’s long-standing record of 24 major titles when she was runner-up at Wimbledon and the US Open.

Tensions boiled over in the New York final when Williams repeatedly clashed with the umpire, in ugly scenes. Roger Federer, who holds the men’s record of 20 Slams, said Williams “went too far”.

Graf said she had no doubt that the 37-year-old American can equal Court’s record.

“She’s shown over and over, it’s incredible what she can achieve,” she said. “There’s nothing, I feel, that says that she can’t.”

Graf added: “She’s got incredible determination. She’s got a strong will and she’s got incredible game and talent.”

Williams has twice held all four major titles, in 2002-2003 and 2014-2015, but she has never swept the trophies in a single season.

The last man to win the calendar-year Grand Slam was Australia’s Rod Laver in 1969 — when he achieved the feat for a second time.

The Ministry of Interior on Friday released a notification to Nhem En, giving him the green light to form the Prosperous Laborers Party as per his request.

He claimed to form the party with a district governor and other formers officials without the intention “to burn the house of other people”.

Pledging to start from reforming the small things, En said: “We will criticise the government but not in a desperate way. I will focus on resolving the environmental and drug issues … these are minor issues that we have not even been able to solve.”

The Interior Ministry also told En to comply with the new articles 19 and 20 of the Law on Political Parties.

The law was passed in 1997 but amended in February last year ahead of local elections to ban convicted criminals from leading political parties.

During the same period, En formed the Khmer Family Party, but was later dissolved by the ministry, along with about 30 others.

“I formed Khmer Family Party but we did not fulfil the required conditions. I started [the party] too close to the elections. Now, I start early, so I can get enough thumbprints to support [the party’s founding],” he said, noting the process “is not difficult”.

“This time, I won’t fail again. I promised to the Prosperous Laborers Party activists that I will try to seek enough thumbprints and later we will hold a party congress.”

The pilot project is twinning technology and fieldwork to locate remains of victims of the Khmer Rouge, the ultra-Maoist regime whose quest to build an agrarian utopia from 1975-1979 left an estimated two million Cambodians dead.

Hacked to death, starved, overworked or ravaged by illness, their bodies were dumped in hastily dug pits all over the country. They were thrown in rice paddies, down caves and on the grounds of Buddhist monasteries.

Many of the “Killing Fields” have been logged, providing experts with an estimate of 20,000 mass graves — which is defined as a pit containing four or more bodies — throughout the country.

But researchers are now turning to radar to uncover more details on the existing sites — such as how many bodies they might contain — and find new ones.

“This is the first time ever that we have used high-end technology in Cambodia to locate mass graves created by the Khmer Rouge,” said Pheng Pong-Rasy from the Documentation Center of Cambodia (DC-Cam), which is overseeing the effort.

He added that DC-Cam decided to start the new search in the eastern province of Prey Veng, where the Khmer Rouge’s revolutionary movement had some of its early gains.

“The children must know their own history, what happened in their location,” he said.

‘How many victims’

They began in late October next to buildings at Mesang High School — specifically plots close to some concrete toilets and an outdoor cafeteria.

The area was once a worship site but the Khmer Rouge converted it into a place for executions. After the regime fell a school was built nearby.

Students and residents helped clear the overgrown area and operators from SparrowHawk Far East, a new Phnom Penh-based company tapped to test out the idea, walked over it sending radar signals below that can later be developed into three-dimensional images.

“When there is an object underground or the ground has been disturbed before, if there was a hole dug, it will give off a different signature,” managing director Michael Henshaw told AFP.

“It’s good for finding underground utilities like water pipes and electric pipes, it’s good for archeology to find old structures underground,” he said. “But it’s also been used to find mass graves.”

Khmer Rouge researchers have since the 1990s relied mainly on meticulous interviews with the regime’s victims and perpetrators to pinpoint the locations of mass graves.

Elsewhere radar has helped locate indigenous burial sites — graves from the Spanish Civil War in 1936-1939 and victims of the 1990s conflict in Bosnia.

In September, it also aided in the discovery of at least 166 bodies in the Mexican state of Veracruz, a territory plagued by drug cartels.

Henshaw said the results can bring about a greater understanding of what happened in Cambodia.

“We can try to put a better number on how many victims there actually were,” he said.

‘Died without justice’

As curious students look on, Henshaw examines preliminary results on a screen while the sun, interrupted by the occasional rainshower, beats down.

He points to what he calls “anomalies”, which look like small ridges next to each other, possibly signifying decomposed remains.

“But this definitely tells you that there is something under the ground, and there’s a lot of it.”

SparrowHawk is plugging the data into special software and preparing a full report on their findings, and DC-CAM will then make a decision on how far to replicate the study.

No matter the results from Prey Veng there will be no excavations and reburials. In keeping with local tradition, the remains will not be disturbed and will will stay where they are.

“They already died without justice, so if we dig up graves, it will destroy their souls,” Pong-Rasy said. “We just want to know how many bodies are in the graves.”

DC-Cam maintains a database of mass graves previously discovered and it has provided information on sites to a war crimes tribunal that has convicted two top Khmer Rouge officials and a chief jailer.

But Youk Chhang, DC-Cam’s director, said the picture is still incomplete.

“Crimes do not end at a tribunal,” he told AFP, adding that a better future for Cambodia required “understanding the horrors” of its past.

“We should not stop searching for the answers”.

Smog kills more than one million Indians every year and Delhi has the worst air of any major city on the planet, the World Health Organization says.

Every November, hospital wards start filling with gasping patients as a tell-tale greyish haze shrouds the city of 20 million.

“Delhi air is like a death sentence for him,” said Srinivas K. Gopinath, a thoracic surgeon at Sir Ganga Ram hospital in the Indian capital where 29-year-old Kumar was treated.

Gopinath fears for his patient, who survived tuberculosis but is now at the mercy of another invisible killer.

As cooler air traps pollutants close to the ground, Delhi’s levels of PM2.5 — particles so tiny they can enter the lungs and bloodstream — often soar to beyond 30 times the safe limit.

One of the worst times is around the Hindu festival of Diwali as smoke from millions of crackers set off by festive revellers mingles with car exhaust, factory emissions, construction dust and smoke from crop fires.

Pollution readings can reach so high they do not register on scientific instruments.

Kumar is due to be discharged from hospital around the time of the festival on Wednesday.

“Inside (the hospital) the air quality is maintained, but once he steps out the bad air will start affecting him,” Gopinath told AFP.

“His resistance is weak. He has only one lung which is now really precious. Imagine having to cope up with such bad air with only one lung?”

‘Black lungs’

But he is far from alone.

Children, the elderly and those with respiratory ailments like asthma suffer the most from Delhi’s hazardous smog, which does not lift until around late February.

Exposure to toxic air kills hundreds of thousands of children every year, the WHO said in an October report.

Children breathe more rapidly than adults, taking twice as much polluted air into their tiny bodies.

It has devastating effects on children in Delhi, say doctors who see it first hand.

“A child who is born in Delhi is taking in gulps of bad air which is equivalent to smoking 20 to 25 cigarettes on the first day of his life,” said Arvind Kumar, a prominent Delhi lung surgeon.

For years the surgeon has tirelessly campaigned to raise awareness about the dangers of air pollution, which the WHO last month likened to the tobacco epidemic.

On hospital grounds this weekend Kumar ordered the installation of giant, artificial lungs fitted with filters to demonstrate the damaging effects of smog.

Many of the patients he sees already bear physical scars from breathing a lifetime of Delhi air.

“These are non-smokers, but even they have black lungs,” he told AFP.

“Even teenagers have black spots on their lungs. This is frightening.”

Despite reappearing every winter, official efforts to combat Delhi’s smog have been ineffectual.

Emergency measures such as banning construction, cutting down traffic and prohibiting the use of diesel generators have had little effect.

More long-term solutions remain elusive. State governments have refused to cooperate on root causes of the crisis, such as farmers using fire to clear their land on the outskirts of Delhi.

Surgeon Kumar said pollution needed to be tackled at its source.

“Everything else is just eyewash,” he said.

The driver of the No 22 bus, a 42-year-old man, quarrelled with a female passenger after she blamed him for missing her stop, according to Chongqing police’s news feed on Sina Weibo, China’s popular social media platform.

Surveillance footage showed the bus veered across the lanes, hit a car, demolished a section of Yangtze River No 2 bridge’s barrier and plunged into the river, where the water is about 70 metres [230 feet] deep. Fifteen people were on board the bus at the time.

Rescue teams, including more than 70 salvage vessels, underwater drones and floating cranes, were sent to the site.

By Thursday, 13 bodies were found and identified, said the police. Two people were missing.

The authorities said they reached their conclusion after studying more than 2,300 hours of surveillance recordings, 220 dashcam video clips, and interviewed the drivers and passengers of 160 vehicles around the site before and after the incident.

Police interviewed 132 other witnesses, including passengers who left the bus before the accident, and bus company employees.

Police divers recovered the bus surveillance camera on Wednesday. Four passengers who got off the bus confirmed that a 48-year-old woman argued with the driver because she had missed her stop. The driver advised her to get off at another stop, but she did not.

Witnesses said the woman realised she had missed her stop and asked to get off. The driver said there were no designated bus stops nearby.

The surveillance recording showed that at 10.03am, five minutes before the accident, the woman stood up from her seat, walked up to driver and began cursing him.

The driver turned his head to face her several times in the argument. At 10.08am, when the bus was on the bridge, the woman hit the driver on the head with her mobile phone. He lashed out at her with his right hand and hit her neck.

The woman then used her mobile phone to strike the driver’s shoulder, while the driver used his right hand to stop her attack and restrain her.

The driver, whose left hand was on the steering wheel all the time, used his right hand to turn the bus, taking the vehicle, at a speed of 51kph, into the opposite lane. It collided with a car and plunged into the river.

The recordings clarified the events leading up to the accident and answered speculation on Chinese social media, police said.

Rumours prompted calls to ban female drivers, as the car that the bus hit was driven by a woman.The car driver was detained by police and later released without charge.

Boston 25 News reported that earlier that day, the after-school instructor from Wellesley, Massachusetts had posted a photo of his ticket to show off on Instagram, leading to him making the account private following the incident.

“I went to ticket services and that’s where I was informed [the] ticket had been scanned at 5:09 p.m., a couple of hours before we got there,” Robbie told Boston 25 News.

He subsequently realized that the photo he had posted showed the barcode and the ticket number, which made it extremely easy for any scammer to duplicate the ticket.

This adds to a collection of stories involving online ticket fraud. Beverly Hills-based ticket sales and distribution company Ticketmaster has been cautioning users with the #CoverTheCode campaign, advising ticket owners not to include barcodes of both printed and mobile ticket in photos posted online.

Boston 25 News further reported that Johnson had to buy another ticket for US$450, but also discovered that whoever had stolen his original ticket, had never sat in his seat.

“There are people who will do these things, which is unfortunate,” Johnson said, “We were very excited about it, never been to a World Series [and it has] always been a lifelong dream of both of ours.”

Johnson attended the game with his sister.

The page quoted his longtime manager Larry Clothier as saying Hargrove died in New York from cardiac arrest following complications from a battle with kidney disease.

“One of the most respected and loved musicians in our New York City community and the world at large, the trailblazing multiple Grammy Award-winning trumpeter was known just as intensely for his brimming fire and fury as he was for his gorgeous, signature balladry,” the post read.

“Over and over, his sound attested to and sanctified his deep love for music. His unselfish timbre covered the waterfront of every musical landscape. Owning his music, his sound, Roy inspired generations of musicians.”

The Texas-born musician, discovered at his Dallas performing arts high school during a visit by legendary trumpeter Wynton Marsalis, developed his talents quickly.

Under Marsalis’s tutelage and encouragement, he traveled to Europe to play at festivals the summer after his high school graduation. By age 25, his star was already on the rise in the contemporary jazz world.

Hargrove went on to play or record with Marsalis and other jazz greats, including Herbie Hancock, Joe Henderson, Stanley Turrentine and Joshua Redman.

He won Grammy awards in two different categories: in 1998 as Best Latin Jazz Performance for “Habana,” and in 2003 for Best Jazz Instrumental with “Directions in Music,” recorded with what was called a post-bop supergroup.
