EL PASO, Texas (Border Report) — Border officers stopped a shipment of ammunition from entering Mexico on Wednesday in El Paso, U.S. Customs and Border Protection said in a news release.

CBP officers conducting southbound inspections stopped a Honda Civic with two female occupants shortly after 3 p.m. Wednesday. Under a blanket in the rear seat, officers discovered 16 boxes of 7.62 mm cartridges. Each box contained 520 rounds of ammunition.
