Cambodia and Thailand forces fought each other for the third day over contested territory as the death toll rose to at least 32 as both sought a cease-fire.

Thailand and Cambodia traded accusations Saturday of fresh attacks as deadly border clashes entered a third day, leaving at least 33 people dead and more than 168,000 displaced, as international pressure mounted on both sides to reach a ceasefire.
