Alexey Zhuravlev cited the "well-proven" Kalibr cruise missile as another option, insisting no international treaties barred such transfers.

Russia said it tested a nuclear-powered cruise missile and torpedo, two of its experimental weapons, in recent days.

President Vladimir Putin on Tuesday praised some of Russia's newest weapons, describing them as faster and more effective, capable of ensuring security and strategic parity and even of use in rare metals extraction and lunar missions.

Russia is testing nuclear weapons, and China is testing them too, you just don’t know about it,” Trump said in an interview that aired Sunday.

Volodymyr Zelensky said he met Ukrainian soldiers near the town of Pokrovsk in Donetsk, where one of the fiercest front-line battles between Russia and Ukraine is underway.

Russian President Vladimir Putin has given state awards to the developers of the Burevestnik cruise missile and the Poseidon underwater torpedo, the latest signal in what analysts have cast as efforts by the Kremlin to discourage the West from supporting Ukraine.
