Belarus extradites a Russian father convicted after his daughter drew an antiwar picture, state news media reports.

Belarus has extradited Aleksei Moskalyov, a Russian father who lost custody of his daughter and fled the country after he was charged for online posts criticizing Russia’s war in Ukraine, Russian state news media reported on Thursday.

Mr. Moskalyov, 54, a single father, was placed under house arrest in early March and charged with “discrediting” the Russian Army over the war in Ukraine. The arrest came after his daughter, Maria, 13, drew an antiwar picture in school. Maria, known as Masha, had been placed in a state-run orphanage after her father’s arrest and forbidden to communicate with him.

At the end of March, Mr. Moskalyov, an ornamental bird breeder, escaped house arrest, hours before a court in Yefremov, a town 150 miles south of Moscow, sentenced him to two years in prison. He was soon detained in Minsk, the capital of Belarus, a Russian ally, and held in a detention center in the town of Zhodino.

On Thursday, the Russian state news agency Tass quoted Natalia Sakharchuk, a spokeswoman for the Belarusian interior ministry, confirming that Mr. Moskalyov had been extradited to Russia. It is not clear whether Mr. Moskalyov would face additional punishment for his escape from house arrest.

Mr. Moskalyov’s posts on the Russian social networks Odnoklassniki and Vkontakte came to the attention of the authorities last April after an art teacher at Masha’s school tried to generate support among the students for the Russian military. Masha’s contribution: a picture of a mother and daughter holding a “Glory to Ukraine” flag and standing in the path of a Russian rocket. “No to War,” she wrote underneath.

His case has attracted international attention, in part because it has thrown custody of his daughter into question.

The Russian authorities have yet to determine whether Mr. Moskalyov’s custody of Masha should be restricted. A hearing last week failed to settle the situation. Maria Lvova-Belova, Russia’s commissioner for children’s rights, said in a post last week on the Telegram messaging app that Masha’s mother, Olga Sitchikhina, had collected her from the orphanage. Ms. Sitchikhina had not been involved in the child’s life since she was 3, according to Vladimir Biliyenko, Mr. Moskalyov’s lawyer.
