Civilian casualties in Ukraine have increased sharply in the past month, the UN Human Rights Office has said.
At least 57 children were killed or injured in March - double the number in February - as Russian forces stepped up their attacks.
The UN Human Rights Monitoring Mission said it had verified at least 604 civilians killed or injured in Ukraine in March, a 20% increase from the previous month.
"The March increase in civilian casualties was mainly due to attacks by the Russian armed forces using missiles and loitering munitions across Ukraine and increased aerial bombardments near the frontline," the Rights Office said.
Most civilian casualties (93.5%), as well as most damage to educational and health facilities, occurred in government-controlled areas.
Volodymyr Zelenskyy warned the country could run out of air defence missiles if Russia keeps up its intense bombing campaign.
The Ukrainian president said last week that Russia fired over 3,000 guided aerial bombs, 600 drones and 400 missiles at Ukraine in March alone.
