LONDON - Britain on Wednesday imposed sanctions on 11 new individuals and entities affiliated with the Russian state, targeting those involved in what it said were Moscow's attempts to forcibly deport and indoctrinate Ukraine's children.

Ukraine says that more than 19,500 children have been taken to Russia or Russian-occupied territory during the war without the consent of family or guardians, calling the abductions a war crime that meets the U.N. treaty definition of genocide. Moscow has said it was protecting vulnerable children from a war zone.

"The Kremlin's policy of forced deportations, indoctrination and militarisation of Ukrainian children is despicable," foreign minister David Lammy said in a statement, setting out Britain's latest round of sanctions against Russia for the war in Ukraine.

Organisations such as the Akhmat Kadyrov Foundation which runs re-education programmes for Ukrainian children and teenagers, subjecting them to militaristic training, and its president, Aymani Nesievna Kadyrova, are among those targeted, the statement said. The sanctions include asset freezes, travel bans and other penalties.

In March, a report by the United Nations Human Rights Office said Russia had inflicted unimaginable suffering on millions of Ukrainian children and violated their rights since its full scale invasion of Ukraine began in 2022.

The Russian embassy in London did not immediately respond to a Reuters request for comment on Britain's latest sanctions.

In March 2023, the International Criminal Court issued warrants for the arrest of Russian President Vladimir Putin and his children's rights commissioner Maria Lvova-Belova related to the abduction of Ukrainian children. Russia denounced the warrants as "outrageous and unacceptable." REUTERS
