“An anonymous message was received by email at Sheremetyevo Airport about the“ mining ”of aircraft following the Moscow-Tyumen, Irkutsk-Moscow, Moscow-Chelyabinsk flights,” the source said.

It is noted that the plane flying from Moscow to Chelyabinsk landed urgently at the airport of Kazan.

On March 5, an A320 passenger plane from Vladivostok landed safely at Novosibirsk Airport after an anonymous mining report.
