Motorbike suicide bomber kills six US troops in Afghanistan
Six American troops were killed in Afghanistan on December 21 when a suicide bomber on a motorbike struck their patrol near Bagram air base, officials said, the deadliest attack on US forces this year.
US Defense Secretary Ash Carter, who stopped briefly at Bagram on December 18, said the deaths were a "painful reminder" of the dangers still faced by US troops in Afghanistan long after fighting has largely shifted to local forces.
Just last week, the Pentagon warned of deteriorating security in Afghanistan and assessed the performance of Afghan security forces as "uneven and mixed."
The Taliban, which claimed responsibility for the strike, remains resilient 14 years after the start of US military engagement in Afghanistan. It has ramped up its attacks this year, inflicting heavier casualties on Afghan security forces.
"Our deepest sympathies go out to the families of these brave Americans who died in service to this vital mission," Carter said. Two service members were wounded along with a contractor.
The Parwan province police chief said three Afghan police had also been wounded in the bombing, which was carried out just days after other suicide attacks on Kandahar air base in southern Afghanistan and on a Spanish embassy guesthouse in the Afghan capital, Kabul.
Bagram, around 40 km (25 miles) north of Kabul, is one of the main bases for the 9,800 US troops left in Afghanistan after international troops ended combat operations last year.
District Governor Abdul Shukur Qudusi said the bomber detonated his explosives near a joint US-Afghan patrol.
The attack underlined the Taliban's ability to hit high-profile targets linked to the US-backed government, which wants to reopen the peace process aimed at ending the 14-year-long insurgency.
