Three Pakistani men have pleaded guilty to trying to smuggle someone they thought was part of the Pakistani Taliban into the United States.

Prosecutors say law enforcement agents worked with confidential sources to ask the three to help get someone they were told was a member of the terrorist group into the U.S. earlier this year. The men were living in Ecuador and are accused of getting the fictitious person a false Pakistani passport.

The three men — Irfan Ul Haq, Qasim Ali, and Zahid Yousaf — each pleaded guilty in federal court to one count of conspiracy to provide material support to a designated foreign terrorist organization. Each faces up to 15 years in prison at sentencing Dec. 9 and has agreed to be deported to Pakistan upon release.
