Thai and Cambodian soldiers fired at each other with machine guns and rocket launchers Friday on a disputed border, an escalation of tension in a long-standing feud near the 11th century Preah Vihear temple. A second gunfight that involved the use of artillery erupted just hours after a morning clash at the same location. There were no immediate reports of casualties. "Fighting is going on now," Maj. Gen. Chea Morn, a Cambodian regional commander overseeing the border area, told The Associated Press. According to Cambodia, Thai soldiers fired first. "Our soldiers were at their positions and Thai soldiers opened fire from their territory," said Phay Siphan, a spokesman for Cambodia's Council of Ministers. A Thai Foreign Ministry spokesman said the ministry was looking into reports of the second clash.
