Dozens of migrants camp on the banks of the Rio Grande on the Mexico-US border in Ciudad Juarez, where they say the Texas National Guard is preventing them from handing themselves over to border patrol agents. "We are waiting to be given our chance but they aren't letting us cross (...) we are despairing for the children, they are fainting with hunger," says one Venezuelan migrant. The Mexico-United States border was the world's most dangerous land route for migrants in 2022, with nearly 700 dying or going missing, according to the UN migration agency. IMAGES AND SOUNDBITES
