Two construction workers died and seven were injured in a traffic accident in Koh Kong province yesterday afternoon, police said.

The victims were on their way to Khemarak Phumin town in the province to set up a marquee for a Thai product exhibition to be held there.

The truck carrying the workers and the marquee parts overturned while descending a slope in Simal village, in Botum Sakor district’s Andong Teuk commune, according to district traffic police chief Pen Sophoan. Two of the passengers were killed when the vehicle tumbled. Three were knocked unconscious.

The survivors were rushed to the Botum Sakor District Referral Hospital. The bodies of the deceased were brought to Andong Teuk pagoda for families to claim for traditional funerals.

According to Sophoan, authorities did not know the victims’ identities as of 7pm yesterday.
