U.S. border agents fired tear gas on hundreds of migrants protesting near the border with Mexico on Sunday after some of them attempted to get through the fencing and wire separating the two countries, and American authorities temporarily shut down border crossings from the city where thousands are waiting to apply for asylum. 

A federal judge barred the Trump administration on Monday from refusing asylum to immigrants who cross the southern border illegally. U.S. District Judge Jon S. Tigar issued a temporary restraining order after hearing arguments in San Francisco.
