Summary of events in Ukraine-Russia crisis on Tuesday

A Russian airstrike hit the main television tower in the heart of Kyiv, killing five people and injuring five more. Ukraine's Interior Ministry said equipment had been damaged and "channels won't work for a while" after a blast sounded in the Babi Yar district.

President Volodymyr Zelenskyy urged the European Union to prove that it supports Ukraine during the invasion by Russia. His comments came in a video link address to the European Parliament one day after he submitted an official request to join the bloc.

More than 70 Ukrainian troops were killed when Russian troops shelled a military base in the town of Okhtyrka, regional governor Dmytro Zhyvytskyy said in a social media post. The town is located between Kyiv and Kharkiv, in the northeastern Sumy region.

Britain's Defense Ministry said in an intelligence update that Russia's advance on Kyiv had made "little progress," citing "logistical difficulties" as the reason for the lack of headway. On Monday satellite pictures showed a massive Russian military convoy spanning a distance of about 40 miles (65 kilometers) inching towards Kyiv.

Advancing Russian forces shelled the central square of Ukraine's second largest city, Kharkiv, hitting the local administration building. The regional governor said that Russia had launched GRAD and cruise missiles.

The UK government said on Tuesday that Russian President Vladimir Putin could face prosecution for war crimes.
