Fighting with Ukraine in Kursk region enters third day, Russia says

Heavy fighting in Russia's Kursk region has entered a third day, with efforts "ongoing" to expel Ukrainian forces from the country, Moscow's defence ministry has said.

At least 1,000 Ukrainian troops, supported by tanks and armoured vehicles, crossed the border on Tuesday, Russia has said.

Some 3,000 people have had to evacuate the region, as ongoing military altercations have killed at least four people, Kursk's deputy Governor Andrei Belostotsky said.

Ukraine's military is yet to directly comment on the reports, but President Volodymyr Zelensky said, without referencing the assault: “Everyone can see that the Ukrainian army knows how to surprise [and] achieve results.”
