With the imminent threat of mass deportations from the United States, Mexican border cities are bracing for an unprecedented influx of arrivals. Across the border from California, the Mexican city of Tijuana receives around 40 percent of all deportees from the U.S. - currently about 125 migrants a day. One of them is Enrique Llamas, who has lived in the city since his deportation from America 14 years ago. "It's considered one of the most dangerous places in the world. I mean, everybody here has so much anger within themselves because life's just not going the way we want it to. It's rough, man, it's about survival," Llamas told China Global Television Network (CGTN). Officials have warned that if U.S. migration authorities deliver on President Donald Trump's stated goals, that volume of deportees may be about to grow significantly. Tijuana Mayor Ismael Burgueno told the press that the city is preparing for "far greater numbers than it has ever seen before" as how many deportees will arrive there is still not sure. According to Victor Clark, a professor at San Diego State University and also director of the Binational Center for Human Rights in Tijuana, the possible even more massive deportations would have a negative impact on all aspects of the city. "The Americans are talking about one million migrants annually, which would mean around 1,000 deported into Tijuana every day. This city does not have the capacity to receive that number of migrants, and it would cause serious economic, social, political and security impacts on the city," he said. With initial enforcement targets set to focus on removing undocumented individuals charged with crimes, the deportee community in Tijuana fears this already-dangerous city is about to take a new downward turn. "Crime is going to go up, and it's going to get pretty dangerous. Who knows what kind of people they're going to be deporting but when you put a lot of rats in a small jar they all tend to go crazy. That's what's going to happen," Llamas said. SHOTLIST: Tijuana, Mexico - Recent 1. Cityscape; 2. Various of people lining up; 3. U.S. deportee Enrique Llamas talking to another man; 4.
