Ukraine is using British Challenger 2 main battle tanks inside Russia’s Kursk, Sky News reported. This is believed to be the first time the UK’s tanks have been used in combat on Russian territory. However, the British Ministry of Defence declined to comment on operational details of the Kursk incursion. This comes as Zelensky claimed Ukrainian forces have taken control of the town of Sudzha after launching a cross-border incursion into Russia’s Kursk region.
