A migrant carries her belongings following a fire at the Moria camp for refugees and migrants on the island of Lesbos, Greece, September 9, 2020. Reuters photographer Elias Marcou: "The morning after a fire broke out at Moria refugee camp on Lesbos island in the olive grove next to it, helicopters were dropping water to extinguish scattered fires, while people were returning to assess the extent of the damage and recover what they could. At the time, approximately 13,000 people were living at the camp, making it the most populated in Europe. The night before, the police had blocked the road a few hundred metres from the camp to prevent refugees from walking to the nearest city of Mytilene, while the camp was ablaze, and people were desperately trying to get away from the flames, carrying with them any personal belongings they could gather in the darkness. Exploding cooking gas canisters gave an intensity to the night chaos. In the grey morning, I watched as a woman carrying some blankets turned back for a moment as if to take a last look at the remnants of the life she was once more moving on from. This thought moved me deeply as I captured this image." REUTERS/Elias Marcou/File photo SEARCH "POY STORIES 2020" FOR THIS STORY. SEARCH "WIDER IMAGE" FOR ALL STORIES. TPX IMAGES OF THE DAY
