Sixty-nine members of a migrant caravan that wound its way from Central American through Mexico to the U.S. border were arrested Sunday after a confrontation with U.S. Customs and Border Protection agents.

The clash between approximately 500 people and U.S. customs agents ended when tear gas was fired at members of the group who were charging toward the border near San Ysidro, California.

The migrants, a fraction of the estimated 6,200 migrants camped in Tijuana, Mexico, were protesting the U.S. policy on asylum, claiming that the process takes too long to complete.

Many of those in the caravan that left Central America in October are camped near the border, trying to gain entry into the United States by applying for asylum.
