KYIV: Ukraine has sunk a Russian submarine and hit a Russian airfield in the past 24 hours, in line with an increase in 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 puts pressure on allies to allow it to use long-range missiles to hit targets in Russia. Western allies, in particular the United States, have so far resisted for fear of escalation from Moscow.
