The Russian Defense Ministry said Sunday that the Ukrainian armed forces used eight drones with suspended ammunition on Saturday to strike the territory where the Zaporizhzhia nuclear power plant is located.

 

Despite the presence of representatives of the UN nuclear watchdog IAEA, the Kiev authorities "continued provocations in order to create a threat of a man-made disaster," the ministry said in a daily report.

 

The radiation situation in the area of the Zaporizhzhia plant remains normal, it added.

Moscow will take serious retaliatory measures if the EU formally introduces visa restrictions on Russian citizens, Kremlin spokesman Dmitry Peskov said Sunday.

 

Russia is closely monitoring the EU decision and the retaliation, symmetrical or not, will definitely meet Russia's interests, Peskov told a local TV program without disclosing what the retaliatory steps could be.
