Russia has launched a massive wave of strikes targeting cities across Ukraine in what the Kremlin said was a response to an attack on the Kerch bridge linking Russia and Crimea.

Barely hours after the Russian president, Vladimir Putin, denounced the bridge attack on Saturday as an act of terrorism" that he blamed on Ukraine's secret services, missiles slammed into the Ukrainian capital, Kyiv, during morning rush hour, striking targets including a popular pedestrian and cycle bridge and a major road junction. Ukrainian officials said at least 10 people had been killed and scores injured.
