This week the Ukrainian government has warned its allies that the army faces nearly 50,000 Russian troops now deployed to Kursk province.
Ukrainian forces have held hundreds of square kilometers of territory inside Russia since a surprise blitz move across the border in early August. Rather than Moscow choosing to relocate sizeable forces from Donbass to defend Kursk, which Kiev was hoping for as a strategic way to weaken Russian front lines in the east, the Kremlin has been patient.
It appears a final big push to force out the Ukrainians is underway. President Volodymyr Zelensky confirmed this in Monday statements. He said that Ukrainian troops "continue to hold back" the "nearly 50,000-strong enemy group" in Kursk.
