Several rockets were fired at Kabul's international airport, witnesses and security sources say. The attack comes less than 48 hours before the US is due to complete its troop withdrawal from Afghanistan. A security official who worked in the administration toppled two weeks ago by the Taliban said the rockets had been fired from a vehicle in north Kabul. The Daesh group, rivals of the Taliban, pose the biggest threat to the withdrawal after carrying out a suicide bomb attack at the airport last week that claimed more than 100 lives, including 13 US troops. As many as five rockets were fired at the airport but were intercepted by a missile defence system, a US official said earlier.
