Afghan and coalition forces conducted sweeps across Afghanistan that left at least 30 militants dead, while insurgents in the east killed five security guards in an ambush on a vehicle convoy, officials said Saturday. Before dawn on Friday, international and Afghan forces carried out an operation in the Sangin district of Helmand province and 10 insurgents were killed, said Daud Ahmadi, a spokesman for the regional governor. Mullah Mohammed Hassan, a «prominent» Taliban commander who was involved in many insurgent attacks in northern Helmand province, was captured in the Sangin village of Pirqadam Kariz during the raid, Ahmadi said. No security forces or troops were injured in the operation, he was quoted as saying by the Associated Press.
