PHNOM PENH — Four workers are missing and presumed drowned after an under-construction dam partially collapsed in western Cambodia, officials said Sunday. Maj. Theang Leng, chief of the police in the district where the hydroelectric dam is located on the Atay river, said the midday Saturday collapse appeared to occur because the dam was holding too much water and had started leaking. A search was under way for the missing workers. Another four workers were seriously injured. — AP
