“Nearly two-thirds of Ukraine’s children are displaced – whether displaced inside the country or those who have fled across borders as refugees,” said Afshan Khan, regional director for Europe and Central Asia.

Khan said that according to UN figures, 277 children have been killed and 456 injured over the course of the war, and fighting has damaged or destroyed one in six “UNICEF-supported ‘safe schools’” in the country’s east.

The Ukrainian government quotes an even higher figure: The Prosecutor General says 313 children have been killed and 579 injured.
