As seen with a thermal camera, Ecuadorian immigrant Sharick Rios, 62, awaits transport from the U.S.-Mexico border on Dec 7, 2023 in Lukeville, Arizona. A surge of immigrants illegally passing through openings cut by smugglers in the border wall has overwhelmed U.S. immigration authorities, causing them to shut down several international ports of entry so that officers can help process the new arrivals. Thermographic cameras create images based on radiant heat energy, making it possible to see people and objects in total darkness. - Photo by AFP
