JOIN USMohammad Aslam Yar, a spokesman at Kandahar airbase, said the accident involved a fighter jet of the NATO-led International Security Assistance Force (ISAF), which is helping Afghan troops battle a Taliban insurgency.
"At 7:20 am this morning an ISAF airplane crashed in Kandahar airbase," Yar said by phone from the southern province.
"There were two pilots who ejected and were taken to a military hospital inside the base for treatment. Apart from that there are no other casualties. No enemy fire was involved, the plane is still burning."
He did not reveal the nationality of the pilots.
Squadron Leader Keith Cranswick, a NATO spokesman in Kandahar, said the accident happened soon after take-off from the airfield, which is in a province troubled by some of the deadliest insurgent violence in the country.
"It happened right after taking off when something went wrong... The crew ejected," he said.
ISAF confirmed the crash in a statement and said the incident was under investigation, but ruled out insurgent activity as the cause.
