We are completely checking all the helicopters that were in the system of the Ministry of Internal Affairs," the head of the Ministry of Internal Affairs said at the telethon.

According to Klymenko, this process will drag on, perhaps for a month or two, until it is established, together with foreign experts, that these helicopters are safe.
