Ukraine launched a major drone attack on Moscow on Tuesday though all of them were destroyed by air defence systems, Russia's defence ministry said.

The attack came just weeks after the Kremlin was hit in a drone strike that Russia blamed on Ukraine, and simultaneously with the latest wave of Russian airstrikes on Kyiv.
