ISOC spokesperson Maj-General Thanathip Sawangsaeng confirmed that the news circulated on social media was just a rumour.

A message that appeared to be a state announcement that Ratchaprasong intersection, Siam Square, Victory Monument, Democracy Monument, all city railway stations, Hualamphong Railway Station and all bus terminals were under tight security has been widely circulated on Line.

However, the spokesman said no such announcement has been made, adding that police officers will be providing security at the bomb-blast sites, not soldiers.

Thanathip also said that ISOC will welcome any additional information about the incidents, adding that the agency will coordinate with other agencies about the intelligence gathered.
