A secret tunnel used for smuggling migrants and drugs between El Paso and Ciudad Juarez has been discovered along the US-Mexico border. The tunnel, described as sophisticated and equipped with lighting and ventilation, was uncovered during a joint operation involving U.S. Border Patrol and Mexican authorities. Officials indicated that the tunnel was constructed within the past year and is part of a changing smuggling strategy by cartels. In response to this discovery, authorities have begun sealing the tunnel to prevent its further use. Congressman Gonzales expressed concerns over the implications of such operations amid ongoing border challenges.
