An Azerbaijani minister suggested Friday that an airliner that crashed this week was hit by a weapon, citing expert analysis and survivor testimony indicating that the plane was struck from the outside.

Sources told Reuters the plane had been hit by Russian fire. "It was as if it was drunk - not the same plane anymore," one passenger recalled.

It comes as the head of Russia's civil aviation agency says the situation in Grozny, the plane's destination, was "very complicated" at the time.

"No one claims that it was done on purpose," an Azerbaijan official told Reuters. They added their government "expects the Russian side to confess."

The crash of the Azerbaijan Airlines flight prompted several airlines to suspend flights to Russia.

Experts say evidence in the Azerbaijan Airlines plane crash in Kazakhstan points to a possible midair explosion, not an encounter with a flock of birds.
