A caravan of about 1700 Central American migrants arrived at the Mexican border city of Piedras Negras on its way to the U.S.
The governor of Mexico’s Coahuila State says the migrants arrived on 49 buses late Sunday and are still waiting to enter Eagle Pass.
But the U.S. Department of Homeland Security says those with the caravan will not be allowed in.
Border patrol agents are on the bridge connecting Mexico and the U.S., they have riot gear and shields in case they are needed.
A shelter has been set up for the migrants at an unused factory on the Mexico side.
Mexican officials say the group includes 46 unaccompanied minors between the ages of 15 and 17.
