SAMRAONG, Cambodia (Reuters) -On Cambodia's northwestern border, residents staying in makeshift refugee shelters were waiting to head home on Tuesday after a fierce five-day conflict with neighbouring Thailand ended in a ceasefire effective from Monday night.

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 and Cambodia have agreed to “an immediate and unconditional ceasefire” starting at midnight, Malaysian Prime Minister Anwar Ibrahim said.

The State Department raised both advisories to Level 2 on July 25, citing the “risk of unrest” in Thailand and crime and landmines in Cambodia.

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.

Long-festering tensions over border territory have escalated into armed conflict between Cambodia and Thailand, leading to dozens of deaths on both sides and displacing tens of thousands of people
