U.S. agents fire tear gas into Mexico at ‘violent mob’ near border

U.S. border agents launched tear gas into Mexico early on Tuesday to deter a group of migrants that one official called “a violent mob” from crossing over from Tijuana, according to a Reuters witness and the U.S. government. One migrant picked up a canister and threw it back into U.S. territory. U.S. officials said the group had attacked agents with projectiles but a Reuters witness did not see any migrants throwing rocks at U.S. agents.
