TIJUANA, Mexico: Mexico deported scores of Central American migrants arrested after hundreds forced their way through a Mexican police blockade and headed for the United States but were met with tear gas and rubber bullets.

Around 500 men, women and children, part of a caravan of roughly 5,000 mainly Hondurans who have been trekking toward the US for weeks, scrambled over a rusted metal fence and surged into a concrete riverbed toward San Diego on Sunday (Monday in Manila).
