US shuts border after migrants try to cross

TIJUANA, Mexico - US 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.

Authorities also shut down all traffic at the busy crossing between San Diego, California, and Mexico's Tijuana, where thousands are waiting to apply for asylum.

The situation devolved after the group began a peaceful march to appeal for the United States to speed processing of asylum claims for Central American migrants marooned in the Mexican city.
