51 killed in Russian missile strike in Ukraine 

At least 51 people were killed and hundreds injured in a Russian missile attack on the Ukrainian city of Poltava Tuesday. 

It was the war's deadliest single attack this year.

Ukrainian President Volodymyr Zelenskyy said in a video that Russian forces struck with two ballistic missiles, damaging a building of the Military Institute of Communications.  He ordered a full and prompt investigation.

Photographs posted on social media in Ukraine showed several bodies lying on the ground covered in dust and debris, with the badly damaged side of a large building behind them.
