text: About 200 migrants from Central America who traveled in a caravan through Mexico are camped outside the entrance of the San Ysidro port of entry, after being turned away Sunday by U.S. Customs and Border Protection officials on April 30, 2018. So far, none of the migrants from Central America seeking asylum in the U.S. have been allowed into the port to be processed, said Irineo Mujica, of Pueblo Sin Fronteras, the transnational group that organized the caravan.
