Some nine Thai soldiers were wounded in a bomb attack by suspected insurgent on Thursday in a southernmost province of Yala. The suspected militants planted explosive devices in a gas tank and left it at the bridge side in a village of Dta-bheung-dti-ngi in Ban-nang-star district of Yala, Thai News Agency reported. As a car carrying the security force on their patrol task was arriving at the bridge, the bomb went off injuring the soldiers. The attack occurred as acting National Police Chief Pol. General Patheep Tanprasert is visiting the deep South to inspect the situation amid the daily escalating violence attack. Thailand's deep South comprises mainly the three southernmost provinces of Yala, Pattani, Narathiwas, and some parts of Songkla province. Over 3,500 people have been killed by the daily violent attack by the suspected separatists since January 2004.
