Russia’s Defence Ministry said that air defences shot down 10 US-supplied Ukrainian missiles targeting the Crimean Peninsula early Wednesday, as US Secretary of State Antony Blinken spent a second day visiting Kyiv, and Ukraine’s army battled to contain a front-line push by the Kremlin’s forces.

The ATACMS long-range ballistic missiles were destroyed over the Black Sea, the ministry said. The US included the Army Tactical Missile System, known as ATACMS, in a military aid package in March.
