Russia's nuclear-capable Oreshnik missile system has entered active service, Russia's Ministry of Defense said Tuesday, as negotiators continue to search for a breakthrough in peace talks to end Moscow's war in Ukraine.
Troops held a brief ceremony to mark the occasion in neighboring Belarus where the missiles have been deployed, the ministry said. It did not say how many missiles had been deployed or give any other details.
Russian President Vladimir Putin said earlier in December that the Oreshnik would enter combat duty this month. He made the statement at a meeting with top Russian military officers, where he warned that Moscow will seek to extend its gains in Ukraine if Kyiv and its Western allies reject the Kremlin's demands in peace talks.
The announcement comes at a critical time for Russia-Ukraine peace talks. U.S. President Donald Trump hosted Zelenskyy at his Florida resort Sunday and insisted that Kyiv and Moscow were ''closer than ever before'' to a peace settlement.
However, negotiators are still searching for a breakthrough on key issues, including whose forces withdraw from where in Ukraine and the fate of Ukraine's Russian-occupied Zaporizhzhia nuclear power plant, one of the 10 biggest in the world. Trump noted that the monthslong U.S.-led negotiations could still collapse.
Putin has sought to portray himself as negotiating from a position of strength as Ukrainian forces strain to keep back the bigger Russian army.
At a meeting with senior military officers Monday, Putin emphasized the need to create military buffer zones along the Russian border. He also claimed that Russian troops were advancing in the eastern Donetsk region of Ukraine and pressing their offensive in the southern Zaporizhzhia region.
Moscow first used the Oreshnik, which is Russian for ''hazelnut tree,'' against Ukraine in November 2024, when it fired the experimental weapon at a factory in Dnipro that built missiles when Ukraine was part of the Soviet Union.
