A man who the FBI said wanted to wage violent jihad in Africa pleaded on guilty on Friday to a charge of conspiracy to provide material support to terrorists.

Randy Lamar Wilson, 26, pleaded guilty in federal court in Mobile. Under a plea agreement with prosecutors, he could face 15 years in federal prison, contingent on the information he provides about co-conspirators. U.S. District Judge Kristi DuBose set an Oct. 18 sentencing date for Wilson.

Wilson was arrested in December at the Atlanta airport while boarding a flight with his family to Mauritania.

The same day, agents arrested 25-year-old Mohammad Abdul Rahman Abukhdair, Wilson's former business partner. Charges against Abukhdair are still pending and his trial is set for August.

Federal prosecutors portrayed Wilson as an Islamic radical who wanted to reunite with Omar Hammami, an American who also grew up in Alabama and became one of the most well-known jihadists in Somalia.

Wilson told DuBose on Friday that he believed the government could prove that he intended to participate in violent jihad overseas.

Federal prosecutors said Wilson intended to "murder, maim and kidnap" people overseas.
