Suspected Muslim insurgents staged the most deadly coordinated attacks in years in Thailand's restive south, killing 14 people and wounding 340 with car bombs that targeted Saturday shoppers and a high-rise hotel frequented by foreign tourists.

A first batch of explosives planted inside a parked pickup truck ripped through an area of restaurants and shops in a busy area of Yala city, a main commercial hub of Thailand's restive southern provinces, said district police chief Col. Kritsada Kaewchandee.

About 20 minutes later, just as onlookers gathered at the blast site, a second car bomb exploded, causing the majority of casualties. Eleven people were killed and 110 wounded by the blasts.
