Thai police investigators say anti-government militants were responsible for the deaths of at least 12 people in political violence earlier this year.
Head of the Department of Special Investigation, Tharit Phengdit, said Tuesday that evidence and witnesses led to that conclusion after a probe into two months of unrest in central Bangkok in which about 90 people died. No definitive conclusions have yet been reached in the other cases, he said.
The army cleared the streets of the so-called Red Shirt demonstrators on May 19. They had been demanding that prime minister Abhisit Vejjajiva call early elections, claiming he came to power undemocratically.
Protesters say troops using live ammunition used excessive force in the crackdown.
