Phnom Penh  - Cambodian and Thai soldiers exchanged gunfire Friday morning at a disputed border area where a fatal skirmish between the South-East Asian neighbours erupted last year, a government spokesman in Phnom Penh said.

No casualties were reported in the clash at the ninth-century Preah Vihear temple, government spokesman Phay Siphan said.

He said about a dozen Thai troops crossed the border about 7.15 am (0015 GMT) and were immediately confronted by Cambodian soldiers.

The firefight came a day after a Thai soldier was badly injured by a landmine at the site, which both countries claim falls within their territory.

Both countries amassed troops at border in July after the temple was declared a UNESCO World Heritage Site. (dpa)
