KYIV, Ukraine >> Ukraine’s government on Sunday called for an emergency meeting of the U.N. Security Council to “counter the Kremlin’s nuclear blackmail” after Russian President Vladimir Putin revealed plans to station tactical atomic weapons in Belarus.

One Ukrainian official said Russia “took Belarus as a nuclear hostage.”

Further heightening tensions, an explosion deep inside Russia wounded three people Sunday. Russian authorities blamed a Ukrainian drone for the blast, which damaged residential buildings in a town just 175 kilometers south of Moscow.

Russia has said the plan to station tactical nuclear weapons in Belarus comes in response to the West’s increasing military support for Ukraine. Putin announced the plan in a TV interview that aired Saturday, saying it was triggered by a U.K. decision this past week to provide Ukraine with armor-piercing rounds containing depleted uranium.

Putin argued that by deploying its tactical nuclear weapons in Belarus, Russia was following the lead of the United States. He noted that Washington has nuclear weapons based in Belgium, Germany, Italy, the Netherlands and Turkey.

“We are doing what they have been doing for decades, stationing them in certain allied countries, preparing the launch platforms and training their crews,” he said.

Ukraine’s Foreign Ministry condemned the move in a statement Sunday and demanded an emergency meeting of the U.N. Security Council.
