Ukraine has sunk a Russian submarine and attacked a Russian airport in the past 24 hours, officials said, in a move to increase long-range strikes against Russian targets. Russia announced that Ukrainian drones also attacked a residential building and killed one person. The increase in attacks since July comes as Ukraine pressures its allies to allow it to use long-range missiles to attack targets in Russia. Western allies, particularly the United States, have so far resisted for fear of an escalation by Moscow.
