Barrage of Russian strikes on key infrastructure in Ukrainian cities

A massive barrage of Russian strikes on Monday morning hit critical infrastructure in Kyiv, Kharkiv and other cities in apparent retaliation for what Moscow alleged was a Ukrainian attack on its Black Sea Fleet over the weekend.

Loud explosions were heard across the Ukrainian capital in the early morning as residents prepared to go to work.

Some of them received text messages from the emergency services about the threat of a missile attack, and air raid sirens wailed for three straight hours.

Large areas of the city were cut off from power and water supplies as a result, Kyiv Mayor Vitali Klitschko said.
