Dozens of villagers clashed with riot police in northern Jordan on Monday, two days after some 400 people from the area were hospitalized for poisoning. The riots erupted at sundown, with Sakeb villagers pouring into the streets, burning tires and hurling stones at the local government office, said Ahmed al-Zoubi, the mayor of the town of al-Murab, which also oversees Sakeb. Earlier Monday, Prime Minister Marouf al-Bakhit, accompanied by health, water and environment ministers, toured Sakeb, visiting a handful of the patients who remain in a local hospital there. Some 400 people from Sakeb were admitted to the area's hospitals on Saturday with diarrhea, vomiting and high fever. It was the third such case of mass affliction in the region in four months. Health officials have said the latest poisoning was being investigated, adding that initial reports pointed to either contaminated water or food items sold at a fast food joint in Sakeb.
