Six American service members were killed in a suicide attack in Afghanistan on Monday, U.S. officials told NBC News.
Two other Americans and an interpreter were wounded, the officials said.
The service members were on a routine security patrol around Bagram Airfield when an attacker rode up on a motorcycle and detonated his suicide bomb, the officials said.
U.S. officials did not specify the total number of Americans involved in the incident.
Bagram is a large U.S. military base north of Kabul, the Afghan capital.
Parwan provincial police chief Gen. Zaman Mamozai told NBC News that a suicide bomber on a motorcycle attacked a convoy of Afghan and Western forces at around 1 p.m. local time.
The Taliban posted a message on Twitter claiming responsibility for the attack.
An attack near Bagram Airfield in September killed one NATO service member.
