He added that “the United Nations has received a message sent by Russia regarding an attack on a hospital in Mariupol, Ukraine, and is circulating it.”
On Wednesday, Alexander Shulgin, the permanent representative of the Russian Federation to the Organization for the Prohibition of Chemical Weapons, said that Moscow would soon send documents to the organization on the danger of provocations using chemical weapons in Ukraine.
Shulgin added that Russia had informed the Organization for the Prohibition of Chemical Weapons of a planned provocation by Ukraine at an experimental nuclear reactor in Kharkov.
And the Russian Defense Ministry announced, earlier, the readiness of Ukrainian nationalists to carry out provocations in the city of Kharkov.
“On the night of March 9, about 80 tons of ammonia were shipped to the village of Zolochev, northwest of Kharkov, by Ukrainian nationalists,” the ministry said in a statement.
The ministry added: “The residents who got out of there say that the nationalists teach them how to act properly in the event of a chemical attack.”
