The Ukrainian capital Kyiv has been targeted by further Russian air attacks, described by one official as exceptional in density.

Ukraine said all 18 missiles were shot down and footage showed air defences destroying targets over the city.

At least three people were injured during the barrage, which used both drones and missiles, officials said.

Russia has stepped up its air campaign in recent weeks, ahead of an expected Ukrainian offensive in the south.

Russia’s resumption of strikes on Kyiv earlier this month came after a lull of over 50 days.

The Ukrainian authorities believe Moscow’s strategy is to exhaust the air defence systems, which have been extremely successful in intercepting most of the missiles and drones fired.
