Four men and two women were arrested in the states of Kelantan, Pahang, Malacca, Johor and Penang. Two of the men are suspected of smuggling in arms from southern Thailand.

One of the woman, aged 26, was detained by Turkish authorities in February while she was awaiting instructions from Malaysian terrorist, Muhammad Wanndy Mohamed Jedi, to enter Syria. The other woman allegedly promoted ISIS through the Google Plus application.

As for the remaining two men, one of them had returned from militant activities in Syria, while the other allegedly used 15 Facebook accounts to propagate ISIS agenda and had plans to attack Shi’ite mosques in Penang.
