Bangkok (VNA) – At least six Thai police officers were wounded in an unusual explosion in a border area between Thailand and Malaysia in the southern province of Narathiwat on May 5.

Thai authorities said that attackers detonated a bomb from Malaysia when Thai police officers were patrolling in Tak Bai district, where a small river separates two countries.

Captain Boonsanit Khiewpradit of the Tak Bai police station said that authorities discovered evidence showing that the bomb was placed in a roadside with wires linking to the other side of the river in Malaysia’s territory.

The attack occurred while violence escalates in southern Thailand. Last week, security forces of Thailand suffered a bloodiest attack in two years as six border soldiers were killed in an ambush.-VNA
