U.S. Customs and Border Protection (CBP) has warned agents in an internal security memo to be on high alert after the Mexican military seized nearly a dozen improvised explosive devices (IED) near the border, according to a report.
Mexican authorities found the IEDs after a Tucson, Arizona, border patrol agent reported gunshots near the border, leading to the arrest of an individual on the U.S. side of the border armed with an AK-47, according to Fox News.
