The U.K. has slapped sanctions on North Korea’s largest international children’s camp in a broader move targeting dozens of Russia-tied entities and individuals involved in the alleged indoctrination of Ukrainian children.

Calling the new sanctions package one of the toughest to date, London designated the Songdowon International Children’s Summer Camp on Monday, accusing the institution of “engaging in and providing support for … Russia’s programme for the forced deportation and re-education of Ukrainian children.”

The U.K. accused the camp of providing “support for policies or actions which undermine or threaten the territorial integrity, sovereignty or independence of Ukraine,” according to
