The gang members are crossing with up to 1 million migrants from three Central American countries – El Salvador, Guatemala and Honduras – who are expected to enter the US illegally this year in a bid for political asylum, according to US officials.
The MS-13 gang — previously known as La Mara Salvatrucha — reportedly emerged in 2012 as transnational criminal organization.
