2015 Bagram Airfield bombing
On 21 December 2015, a suicide bomber on a motorcycle attacked a NATO-Afghan foot patrol near Bagram Air Base, killing six American service members and wounding two other Americans and an Afghan. The Taliban claimed responsibility.

On 21 December 2015, near the village adjacent to Bagram Air Base in Afghanistan, a suicide bomber riding a motorcycle loaded with explosives crashed into a NATO-Afghanistan foot patrol. The attack killed six American NATO service members and wounded two other Americans and one Afghan national.
The six service members killed were all of American nationality: Special Agent Adrianna M. Vorderbruggen, Special Agent Michael A. Cinco, Special Agent Peter W. Taub, and Special Agent Chester J. McBride, all of the U.S. Air Force Office of Special Investigations; and Technical Sergeant Joseph G. Lemm and Staff Sergeant Louis M. Bonocasa, both of the U.S. Air Force Security Forces.
Zabiullah Mujahid, the spokesperson for the Taliban, claimed responsibility for the attack on behalf of the group via Twitter and e-mail.
U.S. Secretary of Defense Ash Carter issued a statement responding to the bombing, saying that U.S. troops were "working diligently alongside our Afghan partners to build a brighter future for the Afghan people" and that their "dedicated efforts will continue despite this tragic event." He extended sympathies to the families of those killed and noted the timing during the holiday season for troops serving overseas.
The White House Office of the Press Secretary also issued a statement expressing "deepest condolences to the families of the six U.S. service members killed and to all of those injured" in what it described as "today's Taliban attack near Bagram Airfield in Afghanistan." The statement condemned the attack as "cowardly" and reaffirmed a continued U.S. commitment to supporting the Afghan people and government, promoting peace and stability in Afghanistan, and countering terrorism in the region.
This bombing was one of several attacks associated with Bagram Airfield during the Afghanistan conflict, following earlier incidents in 2007 and 2014, and preceding a further attack in 2016.
