Three Italian medical workers are among nine people who were detained in an alleged plot to kill an Afghan provincial governor, officials said. They were detained after suicide bomb vests, hand grenades, pistols and explosives were discovered in a hospital storeroom in Lashkar Gah, the capital of the southern province of Helmand, a spokesman for the provincial government said. Police were tipped off about a plot to kill Helmand's governor during a future visit to the hospital, spokesman Daud Ahmadi said. A video of the raid shows British troops accompanying Afghan police, soldiers and government officials to the city's Emergency Surgery Center for Civilian War Victims, run by the Italian private group Emergency.
