Russian President Vladimir Putin has warned that Moscow will respond with "several times more powerful" strikes if Ukraine continues attacking Russian territory. Speaking in Moscow, Putin said Russia's retaliation would always be reciprocal while insisting the country's energy sector would recover despite repeated Ukrainian strikes. He also revealed work had begun on a new supply system for Crimea that he claimed would be difficult for Ukraine to target. The remarks come as Russia says it intercepted fresh Ukrainian drone attacks, underscoring the continuing escalation in the war.
