ISIS operating base few miles from Texas border, group warns

Islamic State fighters are operating training bases near the U.S. southern border and are being aided by violent drug cartels to smuggle terrorists into states like Texas, a report published Tuesday by a watchdog group claims.

The Judicial Watch report, which cited an unnamed Mexican Army officer and a Mexican police inspector, raises new fears that the fight with ISIS is closer to the U.S. than previously thought.

The report identified the locations of the two bases, and said one is as close as 8 miles from Texas in a town west of Juarez. Mexican authorities found possible evidence -- plans written in Arabic and Urdu -- last week in the town of "Anapra," the sources said. These sources told the watchdog that "coyotes" who work for drug cartels assist in smuggling terrorists between Fort Hancock, Texas, and other undisclosed locations.

The U.S. State Department and the Department of Homeland Security did not immediately respond to an inquiry from to confirm the report. But the Mexican border has long been seen as a potential vulnerability. reported last summer that social media chatter shows ISIS is aware of the porous border, and are “expressing an increased interest” in crossing over to carry out a terrorist attack.
