Day in Photos: Farmers’ Protest in Poland, Preparing New Year’s Fireworks, and Newborn Elephant Calf

Polish farmers line up their tractors and trucks along the road next to the town of Wiskitki, on Dec. 30, 2025, as they protest against the upcoming signing of a trade agreement between the European Union and the South American bloc Mercosur. The EU-Mercosur pact would create the world's biggest free-trade area and help EU members export more vehicles, machinery, wines, and spirits to Latin America. (Wojtek Radwanski/AFP via Getty Images)
