Explosion rocks Kyiv railway station as thousands of women and children are evacuated

An explosion rocked a Kyiv railway station late on Wednesday where thousands of women and children were being evacuated, Ukraine's state-run railway company said, as the U.N. General Assembly demanded that Russia end its invasion.

An interior ministry adviser said the blast was caused by wreckage from a downed Russian cruise missile, not a direct rocket strike, as previously thought. There was no immediate word on casualties and the station building suffered minor damage. Trains continued to run.

Ukraine's second biggest city, Kharkiv, also suffered heavy bombardment on the seventh day of the war but Ukrainians denied Russia's claim that its forces had taken the Black Sea port of Kherson.

A U.S. official also said control of Kherson remained contested and said Russian forces appeared to be getting more aggressive in targeting infrastructure inside Kyiv as its advances slow in the face of fierce Ukrainian resistance.

The invasion has yet to achieve Russian President Vladimir Putin's aim of overthrowing Ukraine's government but it has sent more than 870,000 people fleeing to neighbouring countries and jolted the global economy as governments and companies line up to isolate Moscow.

The United Nations General Assembly voted overwhelmingly to deplore the invasion "in the strongest terms". It demanded that Russia withdraw its forces in a resolution backed by 141 of the assembly's 193 members.
