Explosion at Bagram Airfield injures multiple personnel

An explosion outside an entry control point at Bagram Airfield in Afghanistan Wednesday has resulted in multiple casualties, U.S. Forces Afghanistan said.

The attack comes a day after U.S. Forces-Afghanistan formally apologized for an offensive leaflet that was dropped in the same province as Bagram Airfield. However, a Pentagon spokesman said Wednesday it was too early to say whether the leaflet spurred the attack.

The explosion occurred at 5:38 p.m. local time Wednesday. Multiple personnel injured in the attack were treated at medical facilities on the base, U.S. Forces Afghanistan said.

It was not immediately clear whether any of the casualties were U.S. service members.
