Fighting continued between Thailand and Cambodia in a border dispute despite the prime ministers agreeing to a cease-fire in calls with President Donald Trump.

SISAKET, Thailand/PHNOM PENH July 27 (Reuters) - Thailand and Cambodia have agreed to Malaysia acting as a mediator in their border conflict, the Malaysian Foreign Minister said on Sunday, as the combatants each said the other had launched further artillery attacks across contested areas.

It's now the fourth day of fighting between Thailand and Cambodia and Thais who had to flee their homes on the border are taking refuge in temporary evacuation centers that house thousands.

Thailand claims the ordnance was newly laid, but Cambodia says they are leftovers from a final stint of fighting during the murderous Khmer Rouge regime. Still, soon after the incident, both sides downgraded relations, expelled their neighbour’s ambassador and recalled embassy staff.

As the Cambodia-Thailand border conflict enters its fourth day, monks, dancers, and civilians offer shelter, food, and aid to those over 168,000 people displaced.
