A Thai F-16 fighter jet bombed targets in Cambodia on Thursday, both sides said, as weeks of tension over a border dispute escalated into clashes that have killed at least nine civilians, including a child.

Of six F-16 fighter jets that Thailand readied to deploy along the disputed border, one fired into Cambodia and destroyed a military target, the Thai army said. Both countries accused each other of starting the clash early on Thursday.

"We have used air power against military targets as planned," Thai army deputy spokesman Richa Suksuwanon. Thailand also closed its border with Cambodia.

Beijing expressed deep concern and hopes that both sides will properly address issues through dialogue and consultations.

Foreign Ministry spokesman Guo Jiakun said China would play a constructive role in promoting de-escalation and that it upholds a just and impartial stance

Cambodia's defence ministry said the jets dropped two bombs on a road, and that it "strongly condemns the reckless and brutal military aggression of the Kingdom of Thailand against the sovereignty and territorial integrity of Cambodia".

The skirmishes came after Thailand recalled its ambassador to Cambodia late on Wednesday and said it would expel Cambodia's envoy in Bangkok, after a second Thai soldier in the space of a week lost a limb to a landmine that Bangkok alleged had been laid recently in the disputed area.

Thailand's foreign ministry said Cambodian troops fired "heavy artillery" on a Thai military base on Thursday morning and also targeted civilian areas including a hospital, leading to civilian casualties.

"The Royal Thai Government is prepared to intensify our self-defence measures if Cambodia persists in its armed attack and violations upon Thailand's sovereignty," the ministry said.

Thai residents including children and the elderly ran to shelters built of concrete and fortified with sandbags and car tyres in the Surin border province.

"How many rounds have been fired? It's countless," an unidentified woman told Thai Public Broadcasting Service while hiding in the shelter as gunfire and explosions were heard intermittently in the background.

Cambodia's foreign ministry said Thailand's air strikes were "unprovoked" and called on its neighbour to withdraw its forces and "refrain from any further provocative actions that could escalate the situation".

For more than a century, Thailand and Cambodia have contested sovereignty at various undemarcated points along their 817-kilometre land border, which has led to skirmishes over several years and at least a dozen deaths, including during a weeklong exchange of artillery in 2011.

Thursday's clashes began early near the disputed Ta Moan Thom temple along the border between Cambodia and Thailand, around 360 km east of Bangkok. Thailand's military said nine people have been killed across three border provinces, including an eight-year-old boy in Surin. (Reuters)
