"Russia is shelling the city with bestial savagery," Zelenskyy wrote to accompany the video. "Residential areas where ordinary people and children live are being fired at."
"This must not become ‘just another day’ in [Ukraine] or anywhere else in the world. The world needs greater unity and determination to defeat Russian terror faster and protect lives," he added.
Russia carried out several attacks across Ukraine on Wednesday. Explosive drones near Kyiv hit a student dormitory as well, killing seven people.

The attacks come as Russian President Vladimir Putin hosts Chinese President Xi Jinping in Moscow this week. Xi has proven to be one of Putin's only friends following the invasion of Ukraine, and the two referred to each other as "dear friend" during their meeting.
The pair signed an agreement expanding their economic ties on Tuesday, with Putin touting potential plans for a gas pipeline from Siberia to China.
Xi's visit came just days after the International Criminal Court issued a warrant for Putin's arrest for war crimes committed in Ukraine.
The Russian president had also just visited a captured Ukrainian city for the first time since the invasion began. Putin spent several hours in Mariupol and was filmed inspecting the rebuilding efforts going on in the city.

Xi is may hold a phone call with Zelenskyy sometime after his visit to Moscow. Such a call would be the first personal interaction for the pair since before Putin's invasion.
