Commenting on the escalating fears of a nuclear disaster or conflict, the ministry made it clear on Thursday that nuclear weapons can only be used in an emergency, Reuters reported.

Foreign Ministry spokesman Ivan Nechayev said that nuclear weapons would only be used to respond to a similar attack or to counter any threat to the country's existence.

Last Tuesday, the Russian Defense Minister confirmed that his country does not intend to use nuclear weapons during its military campaign on Ukrainian soil, describing media speculation about the possible deployment of nuclear or chemical weapons as "utter lies."

As for the possibility of a prisoner exchange between Moscow and Washington, Nechayev indicated that work is underway to implement a prisoner exchange deal between the two parties, pointing out that it is engaged in "quiet diplomacy" with the United States over that potential deal, which may include basketball star, Britney. 

Grenier was sentenced on August 4 in Russia to nine years in prison on drug charges, a sentence that US President Joe Biden called "unacceptable." Her attorneys have filed an appeal over her conviction and nine-year Russian prison sentence for drug possession.

The US administration has also repeatedly asserted that Greiner was unjustly detained but at the same time offered to replace her with Victor Bout, a Russian arms dealer serving a 25-year prison sentence in the United States.

It is noteworthy that since the start of the Russian military operation on the territory of the western neighbor, Washington has lined up firmly with Kyiv, supporting it with weapons, equipment, and humanitarian aid.

Thousands of sanctions were imposed on Russia, affecting all sectors, the wealthy and politicians, including senior ministers.
