All strategic bombers Tu-22M3 have been grounded until the end of the probe into the causes of Tuesday’s air crash near Murmansk, a source in the law enforcement has said.

"For now all Tu-22M3 have been banned from flying until the causes of today’s crash become clear," the source said.

A Tu-22M3 bomber crashed on Tuesday afternoon while trying to land at an air base near Olenegorsk, the Murmansk Region. Three crew members died. One survived. A source in the law enforcement said that according to early estimates the pilot’s mistake made in bad weather was to blame.
