Palestinian authorities say raw sewage has swept through a Bedouin village in the northern Gaza Strip, killing at least four people.
Officials say sewage and mud completely submerged at least 25 buildings in Umm Naser village, after the earthen wall of a sewage pool collapsed Tuesday.
Hospital sources say at least 15 people were injured, and residents say scores of villagers are missing.
In 2004, the United Nations warned that the sewage facility was operating well beyond capacity, but local government lacked the financial resources to construct a new facility.
Witnesses say angry villagers threw stones and opened fire on the convoy of Palestinian Interior Minister Hani al-Qawasmi, who went to inspect the damage.
