There has been a fatal plane crash in Afghanistan where at least 11 people have died after a United States (US) Hercules aircraft crashed at Jalalabad Airport.

US Army Colonel, Brian Tribus says six of those killed worked for the US military, while the others were civilian contractors.

The C-130 is a military aircraft primarily used to carry troops and heavy cargo.

Taliban Spokesman, Zabihullah Mujahid said on Twitter that the group shot down the plane, but US officials declined the statement saying there is no indication of such attack.

The US military said it is now investigating the cause of the accident.

The crash came as US planes worked alongside Afghan Forces, to try and recapture the northern city of Kunduz from the Taliban.
