Russian attacks on Kyiv ‘calculated and wicked’, says Zelenskyy

Ukrainian president calls for more air defence from Europe and US after six killed and dozens injured in strikes across capital

Volodymyr Zelenskyy has described Russia's latest attack against Ukraine as deliberate, calculated and wicked", after six people were killed and dozens injured in a wave of night-time strikes across the capital Kyiv.

Shortly after midnight air raid sirens sounded and residents made their way to shelters or lay between two walls in their apartments. Soon afterwards the whine of Shahed drones could be heard in the sky, with heavy machine gun fire from Ukrainian air defences.
