Migrants seeking to enter the United States continue to arrive in Tijuana and other Mexican cities along the U.S. border. Some migrants are traveling in large groups with thousands of people. Others come in groups of just 10 or 12 people. Many walk for days through Central America, then ride buses or trucks for the long trip through the Mexican countryside. In border cities like Tijuana, they find help in shelters operated by aid groups. Angela Escalante is an asylum seeker waiting in Tijuana. She is there with her husband and 7-year-old son. “The situation is very bad, there are no jobs,” she said of her country of Nicaragua, blaming its political violence on the country’s president, Daniel Ortega. “There’s no security so you can’t safely walk the streets,” she added. New arrivals along the border say they also face violence from organized crime and local drug gangs.
