Ukrainian refugee Tatiana Potapova, 62, from Slabozhensky, sits in a room in her rented apartment in Krakow, Poland, February 1, 2023. The day the war began, Potapova’s hometown near the Russian border fell under Russian occupation and she and her family could no longer travel to areas under Ukrainian control. "It was impossible to leave the house, it was scary, Russians were checking everyone," she recalled. But Potapova's daughter, who has diabetes and uses a wheelchair, needed medicine, while her grandson showed symptoms of trauma. In the end, she said they had no choice but to leave, fleeing through Russia and Estonia to Krakow, where her elder daughter lives.  REUTERS/Kacper Pempel SEARCH "PEMPEL ANNIVERSARY REFUGEES" FOR THIS STORY.

Russian troops reached Posad-Pokrovske on Feb. 25 last year, the day after Russia launched the full-scale invasion it calls a "special military operation" in Ukraine. It was as far as they were able to push north, and the area around the small settlement became a no-go zone between enemy forces. The ground is now littered with ammunition boxes, bullet casings and burned out Russian tanks. Mines lay scattered, two unexploded missiles protrude from the earth nearby, deep, narrow trenches snake through fields and house after house lays in ruins.
