A Taliban spokesman and Afghan journalist affiliated with the militant group had earlier said the mysterious crash was a us military aircraft. He also called Taliban claims that additional aircraft had crashed "false".
"All staff and passengers, including key officers of the Central Intelligence Agency, have been killed", he claimed, also sharing on Twitter a video and visuals of a plane with apparent U.S. Air Combat Command markings.
Provincial government spokesman Arif Noori told CBS News on Monday that the plane appeared to have been flying from Kandahar to Kabul, which is about 200 miles to the north.
The UN's findings come days after reports first surfaced that several civilians had been killed in an airstrike in Boka village in northern Balkh province.
The Red Cross official did not share further details of the crash or whether any of his teams had reached the site.
A police spokesman in the province also confirmed the crash but was at the time unable to identify the craft.
A Taliban spokesman claims the group has shot down a U.S. military aircraft over eastern Afghanistan. "The military plane was not a cargo plane".
It is not immediately clear what caused the plane to crash.
A plane operated by Afghanistan's state-owned airline Ariana has crashed in the country's eastern Ghazni province, senior Afghan officials said.
Monday's plane crash is not expected to derail U.S. -Taliban peace talks if it turns out to have been an accident.
The two sides had been negotiating the deal for a year and were on the brink of an announcement in September 2019 when US President Donald Trump abruptly declared the process "dead", citing Taliban violence.
The militant group frequently exaggerates battlefield actions, and the claims could not be confirmed. The U.S. now has 13,000 of the 22,673 foreign troops in Afghanistan, down from a peak of 100,000 in 2011.
