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.

Negotiations are ongoing between the militaries of Thailand and Cambodia on Tuesday, a Thai army spokesman said, even as the Thai side accused Cambodian troops of multiple attacks in violation of a ceasefire that came into effect at midnight.
