A Cambodian government official has sung praise to U.S. President Donald Trump for "bringing about peace" after Thailand and Cambodia agreed to a cease-fire starting at midnight local time on Monday.

The Thai army said Cambodia launched attacks in multiple areas after the cease-fire was supposed to take effect at midnight, but Cambodia said there was no firing in any location.

Thailand has accused Cambodia of "deliberately" violating a ceasefire the two countries had agreed on Monday to end border clashes that have killed at least 33 people and displaced thousands. It's a shaky start for the ceasefire, which was meant to bring an end to five days of bombardment and rocket attacks along the shared border.
