"Signs of genocide": Zelensky calls on international court to investigate Russia

The latest: Ukrainian troops were holding off a massive assault from Russia's military in Kyiv on Sunday, as street fighting erupted in Kharkiv after President Vladimir Putin's forces entered Ukraine's second-largest city.

• Ukraine confirmed that Russian forces blew up a gas pipeline in Kharkiv.
• The United Nations has confirmed at least 240 civilian casualties since the invasion began but says the "real figures are considerably higher."

What he's saying: “We have to call a spade a spade. Russia's criminal actions against Ukraine show signs of genocide. I spoke about this with the U.N. Secretary-General,” Zelensky said.

• Russia has claimed it does not attack civilians, an assertion Zelensky has repeatedly called "a lie."
• "They lied when they said they would not target civilian population. Since the first hours of the invasion, Russian troops have been hitting civilian infrastructure."
• "This is terror," Zelensky added.
• Ukrainian Prime Minister Denys Shmyhal said that Russia was committing "war crimes," per CNN, and deliberately attacking civilians.
