Cambodian Defense Ministry spokesperson Lt. Gen. Maly Socheata accused Thai forces of escalating the violence with bombardment of Cambodian territory early Sunday, followed by a “large-scale incursion” involving tanks and ground troops in multiple areas.

Both countries' foreign ministers agreed that no other country should be involved in the issue, Mohamad Hasan said.

Despite US President Donald Trump's calls for a ceasefire between Thailand and Cambodia, fighting continued on Sunday morning in the border region between the two countries. The Foreign Ministry in Bangkok quoted a military spokesman as saying that Cambodia had opened fire in the morning and hit civilian homes.
