In his evening address on Sunday, Mr Zelenskyy said Ukraine's forces had advanced up to 3km in Russia's Kursk region as part of its ongoing incursion, taking control of two settlements.
His statement came after reports five people were killed and 12 other people injured in Ukrainian shelling in Russia's border region of Belgorod. According to local officials, one of the people injured was a 16-year-old girl who is in a critical condition.
