A rights group has called on Thailand to investigate the use of lethal force by Thai soldiers against Burmese migrants, allegedly resulting in the deaths of three children.

New York-based Human Rights Watch said in a press release Friday that Thai soldiers fired on a truck carrying 13 undocumented migrant workers from Burma on February 25 after the driver failed to stop for inspection.

The rights group said it had obtained photos showing the truck riddled with bullet holes.

Brad Adams, Asia director at HRW, said the soldiers who fired into the truck, apparently without concern for who could be killed or wounded, need to face the consequences.

HRW also called on the Thai government to provide access for investigators and to ensure none of the survivors are deported to Burma while investigations are conducted.
