Three Minnesota men convicted of plotting to join ISIS received prison sentences Monday ranging from 10 years in jail to time served.

U.S. District Judge Michael Davis gave the 10-year sentence to  Zacharia Abdurahman, who pleaded guilty but did not cooperate with the government against the other members of what Davis called a “terrorist cell.”

Prosecutors had sought 15 years in jail for Abdurahman, who said he wasn’t willing to testify against his former friends.

Davis told Abdurahman he was giving him less partly because his parents have become active in the campaign against terrorist recruiting in Minnesota’s large Somali community.
