The head of the European Union's executive Commission, Ursula von der Leyen, has spoken of her outrage at Russia's deadliest onslaught on Kyiv since July - which also damaged the EU's delegation office in the Ukrainian capital, BBC reported.

At least 19 people including four children were killed and dozens more wounded in the bombardment, Ukrainian officials said. 

A five-storey residential building was destroyed, and the EU mission and nearby British Council were damaged  according to BBC.

In a strongly worded statement, von der Leyen said that Russian missiles struck in close proximity to the diplomatic mission: "Two missiles hit in a distance of 50m (165ft) of the delegation within 20 seconds."
