President Volodymyr Zelensky has confirmed for the first time that the Ukrainian military is conducting a cross-border offensive inside Russia's western Kursk region
Late Saturday night, Zelensky said Ukraine was pushing the war onto "the aggressor's territory"
Russia's foreign ministry says its army will deliver a "tough response" to the incursion
On Tuesday, Kyiv launched the surprise attack and has advanced more than 10km (six miles) inside Russia
Russia says 76,000 people have been evacuated from border areas in the Kursk region
This is the deepest raid into the country since Moscow began its full-scale invasion of Ukraine in February 2022
Kyiv and several other regions came under a Russian drone and missile attack overnight, killing two, local officials said
In its latest report on Sunday morning, the Russian defence ministry says that overnight its forces shot down 35 drones and four rockets fired by "the Kyiv regime".
In a brief statement, the ministry says Russia's western Kursk, Voronezh, Belgorod, Bryanks and Orel regions were targeted by Ukraine. It does not mention any casualties or injuries.
We've been reporting this morning on Ukraine's cross-border offensive into Russia's western Kursk region.
Kyiv has advanced more than 10km (six miles) into the territory, which as we mentioned, is the furthest the Ukrainian military has gone since the full-scale invasion began in February 2022.
The region borders with Ukraine - below we've set out a map for reference.

He went on to thank Ukraine's "warriors", and said he had discussed the ongoing operation in Russia with the country's top military commander - Oleksandr Syrskyi.
"Ukraine is proving that it can indeed restore justice and ensure the necessary pressure on the aggressor," Zelensky added.
He did not mention by name Russia's western Kursk region, where Ukrainian troops have reportedly seized several villages and are also threatening to take a regional town.

More than 76,000 people have already been evacuated from the area, and a "counter-terror" regime imposed across three border regions.
This means authorities in Kursk, Belgorod and Bryansk regions can restrict the movement of people and vehicles and use phone tapping among other measures.
Fighting in Kursk appeared to be continuing overnight, with the region's governor, Aleksei Smirnov, saying early on Sunday that there were injured people in a "treacherous" Ukrainian attack.
He earlier reported that 13 people were injured late on Saturday when the wreckage of a downed Ukrainian missile fell on a multi-storey building in Kursk's regional capital.
The governors of Russia's neighbouring Voronezh and Belgorod regions also reported a Ukrainian drone attack overnight. There was no mention of any injuries.
