MINNEAPOLIS (AP) - A Minnesota man who admitted plotting to join the Islamic State group in Syria has been sentenced to time served by a judge who said he hopes to see the man rehabilitated.

Abdullahi Mohamed Yusuf is the first of nine men being sentenced in Minneapolis this week in the plot. The 20-year-old pleaded guilty more than a year ago of conspiring to provide material support to the Islamic State group, and testified against some of the others.

U.S. District Judge Michael Davis sentenced Yusuf to the 21 months he's already served in jail, plus 20 years of supervised release. Davis said it didn't make sense to send Yusuf to prison because the government would miss a chance to help him.

Yusuf promised the judge he wouldn't let him down.

Prosecutors had asked for 42 months, but U.S. Attorney Andy Luger praised Yusuf for his cooperation and said he accepted the sentence.
