Russia has returned three Ukrainian children and one disabled young man to their families with the help of Qatari mediators, the Kremlin’s children’s rights commissioner Maria Lvova-Belova said Thursday.

Lvova-Belova said the children, including two boys, ages 8 and 15, and a 6-year-old girl, had been living with relatives in Russia. “The boys’ mothers are waiting for them in Ukraine. The girl stayed with her great-aunt after her mother passed away, while her father lives in Ukraine,” she wrote on Telegram.

Lvova-Belova added that a young man with a disability was also repatriated.

She posted a photo from the Qatari Embassy in Moscow showing the children, their guardians and a man in a wheelchair, with all faces blurred except for a Qatari diplomat and an unidentified woman.
