This was reported by TASS with reference to the Ambassador of Russia to the United States Anatoly Antonov.

“I have no doubt that the NATO countries, of course, will share with the United States the information that they will receive from their aircraft,” he told diplomats.

According to him, this is "a very serious question, which requires a very careful reflection."

He expressed confidence that "after a certain time, adequate steps will be taken to ensure the security of the Russian state."

Earlier, Deputy Foreign Minister of Russia Alexander Grushko said that the Russian side is exploring all possible options in connection with the withdrawal of the United States from the Don.
