Ukrainian attack on Sudzha - Russia claims gains amid fierce battles

Following a Ukrainian attack on Sudzha in Russia's Kursk region, the city, now a strategic frontline, remains fiercely contested, with both sides claiming gains. The town, a crucial natural gas hub, continues to send Russian gas to Europe despite ongoing hostilities. Russian forces assert they've recaptured nearby villages and launched a state of emergency in Belgorod after a drone attack injured civilians. The Russian government is deploying additional troops as evacuations continue. This surprise Ukrainian offensive has exposed vulnerabilities along the Russia-Ukraine border, challenging Moscow's control.
