The Royal Thai Army said in a statement that the clash happened after Cambodian soldiers started firing near Ubon Ratchathani province in Thailand's east.

Thai soldiers fired back in response to gunshots from Cambodia's border force, leading to an exchange lasting around 10 minutes before the Cambodians requested a ceasefire, according to the Thai army statement.

Cambodian Royal Army spokesperson Mao Phalla confirmed that "there were clashes", but said that Thai soldiers had attacked Cambodian troops who were on border patrol duty in Cambodia's northern Preah Vihear province, which borders Ubon Ratchathani in Thailand.

Mao Phalla did not provide further details.

Neither side reported casualties.

Bloody military clashes between Cambodia and Thailand erupted in 2008 over the site of an ancient Khmer temple in Preah Vihear located near the border.

The row over a patch of land next to the 900-year-old Preah Vihear temple led to several years of sporadic violence, resulting in at least 28 deaths before the International Court of Justice ruled the disputed area belonged to Cambodia.
