Russia has vowed to deliver a 'tough response' to Ukraine's attacks on its border regions, just hours after Ukrainian President Volodymyr Zelensky confirmed his forces launched a surprise military incursion into 'the aggressor's territory'.

Ukraine's incursion into Russia has continued for a sixth day, the largest such attack since the full-scale invasion and unprecedented for its use of Ukrainian military units on Russian soil.

Overnight into Sunday, a Russian drone and missile barrage on Kyiv killed two people - a man and his four-year-old son. In Russia, Kursk's regional governor said a Ukrainian missile shot down by Russian air defences fell on a residential building, injuring 13 people.

Putin's army said Sunday it had halted Ukraine's advance into its western Kursk region in several places, hitting troops and equipment in areas near the border.

It also said it had foiled an attempt by Ukraine to break into another border district of the Kursk region, further to the south from where the bulk of the fighting has occurred so far.

Russia's promise to strike back comes just hours after Zelensky broke the government's silence on the Ukrainian incursion by indirectly acknowledging ongoing military actions to 'push the war out into the aggressor's territory' in his nightly address on Saturday.
