Russian experts state that a plane headed for Moscow has been compelled to land soon after take-off in a suspected hijacking.
The National Anti-Terrorism Committee on Tuesday said that an anonymous man on the flight, bound from the Siberian city of Surgut to Moscow, requested the team to redirect the plane to Afghanistan.
The plane arrived in the city of Khanty-Mansiysk around 230 kilometers (143 miles) toward the west.
It was not promptly clear whether the traveler was equipped and what his requests were.
The board of trustees said the traveler was still onboard the plane, which presently remains on the runway in Khanty-Mansiysk.
