In this Feb. 17, 2016 photo, Pope Francis blesses hundreds of people gathered a few yards away on the U.S. side., as he stands near the U.S.-Mexico border fence along the Rio Grande, in Ciudad Juarez, Mexico. After a brief moment of prayer, Francis walked down the ramp and got back on his popemobile to head for the fairgrounds, where he celebrated his last Mass during a five-day Mexico tour.
