KYIV: 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 US, have so far resisted, fearing escalation from Moscow.
