Thailand's leader vowed on Saturday to keep fighting on the disputed border with Cambodia as fighter jets struck targets hours after U.S. President Donald Trump said he had brokered a new ceasefire.

SURIN, Thailand -- Three Thai civilians were killed as heavy combat continued along the country's border with Cambodia, the Thai military said Thursday, marking the country's first civilian fatalities since the fighting resumed.

The escalation broke the ceasefire brokered in July by Trump who threatened to halt trade talks with the two countries unless they ended the fight.
