KUALA LUMPUR, Malaysia (AP) — Ceasefire talks have started between Thai and Cambodian leaders in Malaysia in an urgent effort to resolve deadly border clashes that entered a fifth day despite mounting international calls for peace.

The breakthrough came after Mr Trump said that Thai and Cambodian leaders were willing to “quickly work out a ceasefire”. The US president said on Sunday he had threatened to pull out of deals to reduce tariffs on both nations unless they agreed to stop fighting.

Thailand and Cambodia exchanged heavy artillery fire for a second day on Friday as fighting intensified and spread, while Cambodia's leader said Thailand had agreed to a Malaysian ceasefire proposal but then backed down.

Thailand bombed Cambodia with F-16 fighter jets on Thursday, as relations between the two countries imploded following clashes on a disputed border near the Emerald Triangle.

The Chairman of ASEAN, Anwar Ibrahim, says Malaysia has contacted both leaders as tensions rise at the Thailand-Cambodia border.

The UK Foreign Office has issued updated advice for travelling to Cambodia and Thailand amid clashes on the border. This morning (July 24), skirmishes broke out at a disputed part of the Thailand-Cambodian border, with troops exchanging fire.

Thailand is a country in Southeast Asia. Myanmar, Laos, Cambodia, and Malaysia border it. The capital city is Bangkok, renowned for its bustling markets, delectable street food, and stunning temples.
