A senior Afghan official Wednesday survived an attack in southern Afghanistan, but another explosion in the region killed five private security guards, officials said. Jan Mohammad Khan, President Hamid Karzai's advisor on tribal affairs, was en route to a local council in Uruzgan province when a roadside bomb was remotely detonated, Juma Gul Hemat, the provincial police chief, said. Khan, who served for several years as provincial governor for Uruzgan, survived the attack, but a child and police officer were injured and one of the vehicles in the convoy was damaged, he said. The explosives were loaded on a motorbike, which was left at the roadside in Deh Rawood district, he said. No group took responsibility for the attack, dpa reported.
