Eleven people including six US soldiers, were killed in a C-130 military transport plane crash on Friday in eastern Afghanistan. The US soldiers were part of a NATO training and counter-terror mission supporting Afghan troops.
The Taliban has claimed the responsibility for shooting down the plane.
“Our mujahideen have shot down a four-engine US aircraft in Jalalabad,” Taliban spokesperson Zabihullah Mujahid said on Twitter.
“Based on credible information 15 invading forces and a number of puppet troops were killed.”
The Taliban are known to make exaggerated battlefield claims, and NATO has so far not given details on the cause of the crash.
The C-130 crash, which occurred at about midnight local time on Friday (1930 GMT Thursday), left six US soldiers and five civilian contractors dead, US Army Colonel Brian Tribus said.
The contractors had been working for “Resolute Support”, the NATO-led training mission.
Jalalabad is situated on a key route from the Pakistani border region -- where many militants are based -- to Kabul, and it has been the scene of repeated attacks in recent years.
Its airport is home to a major military base.
Although NATO gave no immediate indications that the plane crash was due to militant action, Jalalabad airport has come under attack on several previous occasions.
In December 2012, Taliban suicide bombers killed at least five people in an hours-long battle at the airport, the third attack on it that year.
Most NATO combat troops pulled out of Afghanistan last year but a small contingent remains, including roughly 10,000 American soldiers.
The US soldiers, along with other NATO troops and private contractors, are focusing on training Afghanistan’s national security forces.
The C-130 Hercules is a cargo plane built by Lockheed Martin. It is powered by four turboprop engines and is used extensively by the military to ship troops and heavy gear.
It can take off and land on rough, dirt strips and is widely used by the US military in hostile areas.
The crash comes with Afghan forces battling a Taliban insurgency that has blighted the country since the 2001 US-led invasion of Afghanistan.
The stunning fall of the provincial capital, even temporarily, showcased the stubborn insurgency’s potential to expand beyond its rural strongholds in the south of the country.
The Taliban’s recent advances in Kunduz and neighbouring Takhar and Baghlan provinces highlight that a large and strategic patch of northern Afghanistan is imperilled by a rapidly expanding insurgency.
It is also seen as a game-changer for the fractious militant movement that has been dogged by a leadership crisis since the announcement in July of founder Mullah Omar’s death..
