Thailand and Cambodia exchanged fire along their disputed border for a second day on Friday, officials from both countries said, with more than a dozen people reported killed and more than 135,000 civilians evacuated.

Cambodia and Thailand each said the other had launched artillery attacks across contested border areas early on Sunday, hours after U.S. President Donald Trump said the leaders of both countries had agreed to work on a ceasefire.

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

Acting Thai Prime Minister Phumtham Wechayachai accused Cambodia of laying new landmines in the disputed area, resulting in an injury to a Thai soldier.
