Thailand's Prime Minister Anutin Charnvirakul ordered a halt to the joint peace declaration with Cambodia on Monday, following a landmine explosion that injured two Thai soldiers near the shared border.

The decision comes weeks after the two Southeast Asian neighbors signed a joint peace declaration at the ASEAN Summit on Oct. 26.

Speaking to reporters, Anutin said that the planned handover of Cambodian soldiers held as war captives has been postponed.

According to the Thai Army, the landmine incident occurred on Monday morning near the Preah Vihear temple, injuring two Thai soldiers on patrol and causing one of them to lose his right ankle.
