A wave of Russian missiles and drones has struck across Ukraine, killing 21 people, and heavily damaging apartment blocks and other buildings, in an attack on the eve of a Nato summit in Turkey that has exposed widening gaps in Ukraine's air defences.

Fifteen people were killed in Kyiv, Russia's main target, and 56 others were injured in the attacks early on Monday, according to the city's administrative head, Tymur Tkachenko.
