Two bomb disposal policemen were killed in Thailand Saturday when a suspected explosive they were trying to defuse was detonated by a mobile phone.

Authorities said that at least eight people, including four other officers, were wounded in the blast at an open market in Thailand's violence-wracked southern province of Narathiwat.
