Fighting between Thailand and Cambodia persisted Sunday along their shared border despite U.S. President Donald Trump’s appeal for a cease-fire.

The Foreign Ministry in Bangkok quoted a military spokesman as saying that Cambodia had opened fire in the morning and hit civilian homes.

According to the Thai newspaper Khaosod, the attack took place in the Phanom Dong Rak district in the north-eastern border province of Surin.

Cambodia, however, accused Thailand of opening fire early in the morning.

The Cambodian newspaper Phnom Penh Post cited a spokeswoman for the Defence Ministry saying "Thai forces resumed shelling" in the border area in the early hours of Sunday.
