Thai forces “dropped 2 bombs in the area of Poipet Municipality, Banteay Meanchey Province” at around 11am Thursday, the Cambodian defence ministry said in a statement.

Thailand has not commented on the strike as of early Thursday afternoon.

The renewed fighting between the Southeast Asian neighbours this month has killed at least 21 people in Thailand and 17 in Cambodia, while displacing around 800,000, officials said.

The conflict stems from a territorial dispute over the colonial-era demarcation of their 800km border and a smattering of ancient temple ruins situated on the frontier.

Each side has blamed the other for instigating the fresh fighting, claiming self-defence and trading accusations of attacks on civilians.

Cambodia’s interior ministry said Tuesday at least four casinos in the country were damaged by Thai strikes since the fighting began on Dec 7.
