Four workers are missing and presumed to have drowned after the partial collapse of a dam being constructed in western Cambodia, officials said Sunday. Maj. Theang Leng, chief of police in the district where the hydroelectric dam is located on the Atay river, said the collapse Saturday appeared to have occurred because the dam was holding too much water and had started leaking. A search was under way for the missing workers. Four other workers were seriously injured. Theang Leng said construction work was halted as experts survey the damage, according to a report of the Associated Press.
