Ukraine holds about 90 square kilometres of Kursk, as Russia continues drone and missile attacks on Ukrainian cities further from the front

Around 10,000 Russian soldiers are fighting in Russia’s Kursk region, about 90 square kilometres (35 square miles) of which is controlled by Ukraine, Ukraine’s top military commander said.

“We control about 90 square kilometres of territory in the Hlushkov district of the Kursk region of the Russian Federation, and these are our pre-emptive actions in response to a possible enemy attack,” Oleksandr Syrskyi said without elaborating, in remarks released by his office for publication on Sunday.

The Ukrainian military said the activity in this area prevented Russia from sending a significant number of its forces to Ukraine’s eastern region of Donetsk, where some of the heaviest fighting has taken place in the more than three-year-old full-scale invasion.

Syrskyi’s troops are repelling Russian forces along the frontline, which stretches for about 1,200km, where the situation remains difficult, the Ukrainian military said.
