Washington's behavior on the world stage risks direct conflict between the nuclear states, the Russian embassy in the US has warned, media reports said.

"Today, the United States continues to act with no regard to other countries' security and interests, which contributes to an increase in nuclear risks," the embassy said in a statement on its Telegram channel, RT reported.

"The (US) steps to further engage in a hybrid confrontation with Russia in the context of the Ukrainian crisis are fraught with unpredictable escalation and a direct military clash of nuclear powers," the statement said.

The embassy noted that Washington has recently withdrawn from two key arms control agreements, the 1987 Intermediate-Range Nuclear Forces Treaty, which banned certain classes of land-based missiles, and the 1992 Treaty on Open Skies, which allowed for surveillance flights over each other's territories, RT reported.

The embassy urged the US to "take a closer look at its nuclear policy instead of making unfounded accusations against the countries whose worldviews do not coincide with the American ones."

"Our country faithfully fulfills its obligations as a nuclear-weapon state and makes every effort to reduce nuclear risks," the diplomats said.

The statement comes after the US accused Moscow of using the Zaporizhzhia nuclear power plant in southern Ukraine as cover for its soldiers.

The plant, the largest in Europe, was seized by Russian troops during the early stages of Moscow's military operation in Ukraine, which was launched in late February. It continues to operate with Ukrainian personnel under Russian control, RT reported. (AA/IANS)
