Ukraine war: Wave of drone strikes hits several Russian regions

Moscow has vowed Ukraine will "not go unpunished" after drone strikes hit targets in Russia, while Kyiv saw its heaviest bombardment in months.

The drones hit several Russian regions and damaged two military planes, a fuel depot and a microelectronics factory.

Meanwhile Ukrainian officials said most missiles and drones were shot down but two people were killed.

Kyiv has not said that it was involved in the latest attacks, but it rarely comments on strikes inside Russia.

In recent weeks, however, Ukraine is believed to have increased its use of explosive drones to attack targets in Russia.
