MOSCOW, June 1. /TASS/. The explosive power of a Ukrainian drone was sufficient to penetrate the wall of the Zaporozhye nuclear power plant engine room, which is 50 cm thick, Director Yuri Chernichuk told Vesti.

On May 30, a Ukrainian fiber-optic drone struck the engine room of power unit No. 6 of the plant. The damage was recorded by a group of experts from the International Atomic Energy Agency (IAEA). The attack site is located a few meters from the reactor.
