U.S. fires tear gas across Mexico border to stop migrants

U.S. Customs and Border Protection said in a statement later Tuesday that the gas was used to target rock throwers apart from the migrants who were trying to cross.

“No agents witnessed any of the migrants at the fence line, including children, experiencing effects of the chemical agents, which were targeted at the rock throwers further away,” the statement said.

An Associated Press photographer saw at least three volleys of gas launched onto the Mexican side of the border near Tijuana’s beach that affected the migrants, including women and children, as well as journalists. The AP saw rocks thrown only after U.S. agents fired the tear gas.
