Mexico to clamp down on border after chaos

Mexico pledged to shore up security near its border with the United States and local authorities said that 39 migrants were arrested after a peaceful march devolved into chaos when American agents fired tear gas into Mexico to stop some migrants who tried to breach the border.

Mexico’s interior ministry said it would immediately deport those who tried to “violently” enter the US from Tijuana. Tijuana’s municipal government said more than three dozen migrants were arrested for disturbing the peace and other charges stemming from the march.

The vast majority of more than 5,000 Central American migrants, who have been camped out for more than a week at a sports complex in Tijuana, returned to their makeshift shelter to line up for food and recuperate from an unsettling afternoon.

The conflict sparked after the group began a peaceful march to appeal for the US to speed processing of asylum claims for Central American migrants marooned in Tijuana.
