Ceasefire talks between Cambodia and Thailand were underway in Malaysia on Monday after days of deadly clashes on their disputed border sent civilians scrambling for safety and relations between the two neighbors cratering.

BANGKOK (AP) — Thai and Cambodian leaders will meet in Malaysia for talks to end hostilities, a spokesperson for the Thai prime minister’s office said Sunday. This comes following pressure from U.S. President Donald Trump to end a deadly border dispute, now in its fourth day, which has killed at least 35 people and displaced more than 218,000.

Cambodia asks Malaysia to help secure the release of about 20 of its soldiers currently held in Thai military detention.
