Ukraine hits Russian airfield, sinks submarine in Black Sea

KYIV, Ukraine -- Ukraine has sunk a Russian submarine and hit a Russian airfield in the past 24 hours, in line with a surge of long-range attacks against Russian targets, officials said. Russia said Ukrainian drones also hit an apartment building, killing one person.

The uptick in attacks since July comes as Ukraine mounts pressure on allies to allow it to use long-range missiles to strike targets in Russia. Western allies, in particular the U.S., have so far resisted, fearing escalation from Moscow.

Ukraine struck a Russian Kilo-class submarine and an S-400 anti-aircraft missile complex in the Moscow-occupied Crimean peninsula, according to a statement from the General Staff on Saturday. The air defense system was established to protect the Kerch Strait Bridge, an important logistics and transport hub supplying Russian forces.
