Ukraine and Russia blame each other as missile kills at least four in Kursk school

Ukraine armed forces say 84 people were rescued or had medical help after strike in Russian territory that Kyiv holds

Ukraine and Russia have traded blame for a deadly missile strike that killed at least four people in the dormitory of a boarding school situated in a part of Russia's Kursk region held by Ukrainian forces.

Some of the war's fiercest battles in recent months have been taking place in the Kursk region that borders Ukraine, where Kyiv forces have held swathes of the land since staging a major cross-border incursion last August.
