Two youths were left dead Sunday night after a vicious gang fight in the border town of Poipet in Banteay Meanchey province, according to local police.

Om Sophal, the Poipet police chief, said that witnesses had reported that two groups of "gangsters" made up of about five or six people and armed with machetes, had fought like "in a Hong Kong movie".

The two fatally injured during the fighting were brutally attacked, Sophal said. One, known only as Bros, 20, died at the scene, while 30-year-old Som Sal died en route to hospital.

"Until now, our authorities have not discovered the exact reasons behind this savage attack yet, but we have concluded that it is a case driven by spite," he said.

The rest of the gang members fled the scene and remain at-large, Sophal said.
