MINNEAPOLIS (AP) — Federal authorities in Minnesota have charged two men with conspiracy to provide material support to the Islamic State group.

U.S. Attorney Andy Luger says 18-year-old Abdullahi Yusuf and 20-year-old Abdi Nur conspired to travel from Minnesota to the Middle East to "engage in a campaign of terror in support of a violent ideology."

According to the complaint, Yusuf tried to go to Istanbul, Turkey but was stopped by FBI agents at the airport on May 28. Nur departed from Minneapolis for Istanbul on May 29 and didn't return in June as scheduled. Court documents say he's communicated on Facebook that he has gone "to the brothers."

Yusuf is scheduled to appear in U.S. District Court in Minneapolis on Tuesday afternoon. It was not immediately clear if he had an attorney.
