Thailand launched airstrikes along the disputed border with Cambodia on Monday as both sides accused the other of breaking a ceasefire. Longstanding border disputes erupted into five days of combat in July that killed dozens of soldiers and civilians.

US President Donald Trump pushed the Southeast Asian neighbours to sign a truce agreement in October, but tensions have continued to simmer. Thailand said that more than 50,000 people have left areas near the border for shelters, while Cambodia said that residents of several villages near the border have been evacuated.
