KABUL: A Taliban truck bomber killed six people in a province south of Kabul Thursday, officials said, in the first major attack since the insurgents confirmed the death of their leader Mullah Omar. The Taliban claimed responsibility for the attack in Pul-i-Alam, the capital of Logar province in insurgency-prone eastern Afghanistan. An official from the provincial governor’s office confirmed the death toll, adding that eight people including a child were wounded. Thursday’s bombing was the first suicide attack since the Taliban confirmed last week the death of their leader Mullah Omar, who led the militant movement for some 20 years. The attack highlights growing insecurity as Afghan forces face their first summer fighting season without full NATO support.
