Renewed fighting raged at the border of Cambodia and Thailand on Thursday, with combat heard near centuries-old temples, ahead of U.S. President Donald Trump¡¯s planned phone call to the two nations¡¯ leaders.

At least 15 people, including Thai soldiers and Cambodian civilians, have been killed in the reignited border conflict, officials said.

More than half a million people, mostly in Thailand, have fled border areas near where jets, tanks and drones have waged battle.
