Russia threatens Kyiv strikes after Ukraine's election-day drone attacks

Russia promised on Sunday to intensify strikes on Kyiv after Ukraine launched drone attacks on Moscow during Russia's parliamentary elections. An exit poll showed the ruling United Russia party winning the tightly controlled vote. Ukraine fired waves of drones at Moscow and the surrounding region on the final day of voting, officials said. The attacks killed two people and set an oil refinery on fire. Russia's defence ministry accused Ukraine of trying to "disrupt the democratic will of Russian citizens." Moscow said it would respond by escalating its own attacks on the Ukrainian capital.
