Ukraine vowed to strengthen its armed forces after Russia launched its biggest aerial assaults on cities since the beginning of the war, forcing thousands to flee to bomb shelters and prompting Kyiv to halt electricity exports to Europe.
Massive explosions shook the Ukrainian capital and other cities during the morning rush hour on Monday in apparent Russian revenge strikes after President Vladimir Putin declared an explosion on the bridge to Crimea to be a terrorist attack.
Russia denies deliberately targeting civilians. Vladimir Rogov, an official in the Russian-installed administration in the Zaporizhzhia region, blamed the attack on Ukrainian forces.
