A second airman from Stewart Air National Guard Base has been revealed to be among the six Americans that were killed in the Afghanistan suicide bombing.
The individual has not yet been identified publicly.
Six American troops were killed on Monday after a suicide bomber attacked a NATO-Afghan patrol near Bagram air base in Afghanistan.
Three NATO troops were wounded as a result of the attack.
The Taliban claimed responsibility for the suicide bombing, which was the largest attack on foreign troops in Afghanistan since August.
Shoffner said it happened at around 1.30 p.m. local time in the vicinity of Bagram, the largest U.S. military facility in Afghanistan.
Mohammad Asim Asim, governor of Parwan province, where Bagram is located, said that a suicide bomber rammed an explosives-laden motorcycle into the combined NATO-Afghan foot patrol as it moved through a village close to the base, which is 45 kilometers (28 miles) north of Kabul.
He also said that two Afghan police officers were wounded in the attack.
It is the first major attack on a NATO military convoy since August 22, when three American contractors with the RS base were killed in a suicide attack on their convoy in Kabul. On August 7 and 8, Kabul was the scene of three insurgent attacks within 24 hours that left at least 35 people dead.
