Ukrainian President Volodymyr Zelenskyy on Thursday said a Russian missile strike on a nine-story Kyiv apartment building was a sign that more pressure must be applied on Moscow to agree to a ceasefire,

It was the deadliest attack on the Ukrainian capital in almost a year, and came as Moscow has intensified air assaults on the city.

A massive overnight Russian strike on Kyiv, the Ukrainian capital, killed 15 people and wounded at least 177 others, Ukrainian officials said.
