Following the Russian bombing of an art school in Mariupol, where about 400 people had been taking refuge from Russian airstrikes, President Vladimir Putin and his forces are now being accused of abducting about 2,500 Ukrainian children from Donetsk and Luhansk and deporting them to Russia as refugees.

The bombings in Mariupol, which had been under siege since the beginning of the invasion, had been continuous as it had also targeted a local drama theater that had an estimate of 1,300 Ukrainians inside. Furthermore, the Russian forces also bombed a maternity hospital last week, which Russian Foreign Ministry Spokeswoman Maria Zakharova defended by asserting that there were Ukrainian forces within the hospital.

They had also allegedly taken the largest hospital in Mariupol hostage, rounding up civilians from the nearby houses and putting them into said hospital. Reports indicated that the Russians had threatened to shoot those who tried to escape. However, these claims could not be independently verified.

After the bombings, the Russian forces had forcibly rounded up thousands of residents in Mariupol and sent them on their way to remote cities in Russia. Ukraine’s Human Rights Commissioner Lyudmyla Denisova claimed that these Ukrainians were “kidnapped” and transported to Taganrog, the closest Russian city from Mariupol, about 60 miles away. She also stated that Ukrainians were also transported by train to “economically depressive Russian cities.”

“Our citizens were given documents that oblige them to stay in a particular town, meaning they have no right to leave it for at least two years and they have to seek employment there,” she told journalists over at Ukraine’s Channel 24. She also admitted that they did not know what had happened to the other Ukrainians who were forcibly deported, leaving them at the hands of their Russian captors.
