Pattani Governor Wittaya Panitchpong visited three injured people at Pattani Hospital. Five wounded people were at Somdet Phra Yupparat Hospital in Sai Buri district, while 12 of the other injured had been released home.
Meanwhile, PM Yingluck Shinawatra's security adviser, Lt-General Paradorn Pattanatabut, told AFP that security officials in the three southernmost provinces were on heightened alert ahead of the 10th anniversary of a raid on a mosque in Pattani that left 32 insurgents dead on April 28. "But the area is very large," he told AFP.
"Every year militants will stage attacks to display their strength," he said. "The suspension of the peace dialogue has made them exploit the situation and the weakness of the government because of the protests," Paradorn said.
