This is the heart-stopping moment Cambodian rockets fell, sparking panic in a Thai village.

The locals were having their cars checked when explosions were heard near an auto shop in Sa Kaeo province on December 10.

Footage shows terrified villagers scrambling to escape as a blast rang out in the border area.

Some raced off on their motorcycles as residents were heard urging customers: 'Leave, leave! Go first, go first.'

Fighting flared up on Sunday as the Thai army claimed Cambodian troops fired on a Thai engineering team building an access road in a disputed border area.

The Thai military said nine soldiers and three civilians have been killed, while more than 120 personnel were injured.
Cambodia said nine civilians, including a baby, have died and 46 others were wounded.

More than 500,000 people have been displaced on both sides.

Cambodia's assault has largely been wayward, unguided rockets fired indiscriminately into Thai territory, while Thailand has used precision drone strikes and fighter jet strikes on military sites.

The BBC has reported that Thailand has provided 'compelling evidence' that Cambodia has also 'laid new landmines in bad faith' that have continued to injure Thai soldiers along the border.

Former Khmer Rouge henchman and Cambodian dictator Hun Sen - who was a leading figure in the genocide of his own people in the 1970s before assuming power in 1985 and overseeing the murder of thousands of opposition figures and critics - has repeatedly claimed that he wants peace and that Thailand is the aggressor.

Thai officials claim the ongoing border confrontations are a threat to national security, and the areas must be secured.
