A Ukrainian hospital building was destroyed by shelling on Tuesday, according to a Telegram posted by the Ukrainian Parliament.
The post accuses Russian forces of targeting a hospital in the second-largest Ukrainian city, Kharkiv.
U.S. officials have said that Russia is targeting schools, residential buildings and hospitals, but Russia has thus far denied targeting civilians during the conflict.
Ukrainian President Volodymyr Zelensky has called for a war crimes investigation against Russia for their actions.
At least 136 Ukrainian civilians were killed in the past six days of fighting, according to the United Nations, but the total is likely much higher.
Ukraine has endured losses, but remains in control of the capital city of Kyiv. U.S. intelligence has reported over the last week that Ukrainians have been effective in slowing down Russia’s military and putting up more of a successful resistance than expected.
Ukrainian citizens have lined up to receive weapons and basic military training to combat the Russian invasion.
Zelensky has pleaded with Western countries for support, and many have responded, sending weapons and other supplies to Ukraine.
