A federal court hearing continues Tuesday for two Mississippi residents arrested on charges that they were trying to travel to Syria to join the Islamic State militant group.

Criminal charges filed Saturday say 19-year-old Jaelyn Delshaun Young and 22-year-old Muhammad Oda Dakhlalla were arrested that morning at Golden Triangle Regional Airport near Columbus, Mississippi, just before boarding a flight with tickets bound for Istanbul.

The charges say the two, in online communications, repeatedly told undercover FBI agents they wanted to join the group fighting to create an Islamic state.

An affidavit by an FBI agent says both confessed after their arrest.

Both are charged with attempting and conspiring to provide material support to a terrorist group. It was unclear Monday which lawyers represent them.
