Taliban claims responsibility for blasts that kill 14 people
It was unclear how the bomber at US Forward Operating Base Chapman at the edge of Khost city was able to circumvent security. Khost is the capital of Khost province, which borders Pakistan and is a Taliban stronghold.
Taliban spokesman Zabiullah Mujahid said in a statement that an Afghan National Army officer wearing a suicide vest entered the base and blew himself up inside the gym. A US official who was briefed on Wednesday’s blast also said it took place in the gym.
