Central American migrants approached the border on Sunday to call attention to shelter conditions and request asylum, and Border Patrol fired tear gas into Mexico, forcing parents with toddlers to flee. 'Children were screaming and coughing,' the AP reported. 'On the U.S. side, shoppers streamed in and out of an outlet mall.'
U.S. authorities closed off the San Ysidro port of entry, one of the largest border crossings.
'Imagine having tear gas launched at you after escaping gang violence/poverty while carrying your child,' Juan Escalante, a columnist at the Huffington Post, wrote on Twitter.
While Trump Twittered late Saturday to claim that asylum seekers will be forced to stay in Mexico until their cases are processed, Mexican government officials said publicly that no such agreement has been reached.
