Explosion outside Kabul airport killed at least 13 people, including children.

An explosion outside Kabul airport killed at least 13 people, including children, and wounded many Taliban guards, a Taliban official told Reuters. The Pentagon confirmed there were at least two explosions, with no immediate word on casualties.

A US official said that American service members were among the wounded, adding he was citing an initial report and cautioning that it could change. He told the news agency there were casualties but did not know how many or of what nationality.

The United States and allies have been urging people to move away from Kabul airport due to a “very credible” threat of a terror attack by Islamic State (IS) militants as Western troops hurry to evacuate as many people as possible before an August. 31 deadline.
