A member of Mexico's National Guard detains a migrant, part of a caravan travelling to the U.S., near the border between Guatemala and Mexico, in Ciudad Hidalgo, Mexico, January 20, 2020. Reuters photographer Jose Torres: "As I was covering a migrant caravan, thousands tried to cross the border from Tecun Uman in Guatemala to Mexico through military and police lines. This man came out of nowhere. He ran with fellow migrants, shouting words of encouragement, exhorting them to stand their ground and not give in to the police line standing on the Mexican side. It took three policemen to detain him. As the police tackled him to the ground, I went down as well to capture the moment, as he struggled and shouted "Freedom." In the end, he surrendered. The look in his eyes changed as he realized his journey was over. Since 2018, covering the caravans has become very challenging, both physically and mentally. There is a constant chance of the migrants clashing with the police, and the stories of the people travelling are always touching."
