Thai and Cambodian soldiers revived a long-simmering dispute over an 11th century temple near their border, trading fire with machine guns and rocket launchers in clashes that left as many as four people dead. The latest flare-up - if not quickly resolved - could overshadow a summit of Asian leaders opening next week in the Thai coastal town of Pattaya. The summit already was delayed once in December after anti-government demonstrators took over Thailand's two main airports in Bangkok. The fighting broke Friday morning out near the cliff-top Preah Vihear temple, which is on the Cambodian side of an ill-defined border. Soldiers clashed again hours later, but the area was quiet by evening and the two sides were in talks to defuse the crisis.
