U.S. defense officials announced on Monday that three American troops and one American security contractor were killed by a vehicle-borne improvised explosive device in Afghanistan.

The suicide car bombing reportedly happened near Bagram Air Base, an airfield located in northern Parwan province and one of the largest U.S. bases in Afghanistan.

Three Americans were also wounded in the attack.

The injured troops were medically evacuated from the battlefield.

In accordance with Department of Defense policy, the identities of the killed and wounded are being withheld pending notification of next-of-kin.

The Taliban has reportedly claimed responsibility for the suicide vehicle-borne improvised explosive device (VBIED) attack.
