Ukraine accuses Russia of war crimes

Ukraine Prime Minister Denys Shmyhal has accused Russia of war crimes and targeting civilian targets. 

Shmyhal said Russia shelled kindergartens, residential blocks and "buses with children" as a drastic resort because it is "failing" in its offensive. 

"For these crimes, the Russian command will surely see military tribunal. The enemy will surely be punished for killing Ukrainian children. Ukraine will not forgive them for this," Shmyhal said during a news conference on Saturday. 

'Are you on the side of the killers of children, or are you on the side of the great European people who are defending their country?'

"The Russian government doesn't understand they are not fighting only with the government. In fact, they are fighting against the entire Ukrainian people," he said.

Shmyhal also said that Ukraine is temporarily closing its borders with Belarus and Russia except for Ukrainian citizens abroad, who he urged to return and fight. 

"Please do come back and do prove you are on the side of the light. And I'm addressing all civilized countries: On whose side are you on?" he asked. "Are you on the side of the killers of children, or are you on the side of the great European people who are defending their country and they're defending their freedom from the aggression?"
