The United States has confirmed reports of an American communications plane crash in Afghanistan.
Investigations are ongoing into the downing of the Bombardier E-11A in Ghazni, which is a region with a large Taliban presence.
An American military spokesperson said "there are no indications the crash was caused by enemy fire".
Colonel Sonny Leggett, representing US Forces-Afghanistan, denied reports from the Taliban that additional aircraft had crashed.
The number and fate of people on board are yet to be confirmed, with US Defense Secretary Mark Esper refusing to comment further on the incident in the mountainous Ghazni province.
The US is negotiating a reduction in hostilities or a ceasefire with the Taliban, to enable a peace agreement to be signed.
Such a deal could bring home an estimated 13,000 American troops and open the way to a broader post-war deal for Afghans.
Peace progress has been fragmented in recent weeks, however.
Earlier this month, the Taliban claimed responsibility for the deaths of two US soldiers on NATO's Resolute Support mission in Kandahar.
In December, Taliban officials told reporters that a temporary, nationwide ceasefire had been agreed by its council leaders.
Hours later, however, fourteen members of Afghanistan's security forces were killed after the Taliban targeted a pro-government militia compound in the north of the country.
A provincial spokesperson said the plane went down around 1:10 pm local time (8:40 am GMT), 80 miles south-west of the Afghan capital, Kabul.
He said the crash site is in territory controlled by the Taliban, who are believed to control around half of the Middle Eastern country.
The Bombardier aircraft enables better communications between air and ground forces and between different types of aircraft operating in difficult terrain.
