Cambodia and Thailand agreed to an "immediate and unconditional" ceasefire Monday after five days of intense fighting along their shared border. The ceasefire, negotiated in Malaysia with involvement from the U.S. and China, took effect at midnight.

Intense nationalism and disputed history — and maps — stoke the neighbors’ hostilities. Even a surge of international diplomacy has brought little hope of a lasting peace.

The fighting, which began last Thursday after a land mine explosion injured Thai soldiers, has killed at least 35 people and displaced over 260,000 people.

A ceasefire between Thailand and Cambodia appeared to largely be holding on Tuesday as military commanders from both countries met for negotiations, even as the Thai army accused Cambodian troops of violating the truce overnight.

Thailand's military said that there had been attacks by Cambodian troops in at least five locations early on Tuesday, violating the ceasefire.

Thailand’s military accused Cambodian forces on Wednesday of breaching a ceasefire agreement at three separate locations along the disputed border, warning that continued aggression could compel Thai forces to respond more decisively.

The conflict is one of the deadliest clashes ever between the two countries. Thirty-four people have died, and over 165,000 have been displaced.

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.

Thailand has estimated the initial costs of evacuation and damaged property at more than 10 billion baht ($307.88 million) after a five-day border conflict with Cambodia, and is expecting the eventual economic impact to be even bigger,

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.

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

Livestock offices in Thailand's border provinces are offering safe space for animals whose owners have had to flee the fighting with Cambodia.
