US federal authorities have arrested six people in Minnesota and California as a part of an investigation into young men who are trying to travel to or have travelled to Syria to join the Islamic State (IS) militants.
According to Fox News, a spokesman for the U.S. Attorney's Office in Minnesota said that there is no threat to public safety.
A spokesman for the Minneapolis FBI office confirmed the number of people arrested.
According to reports, three of the men arrested in Minneapolis were already known to authorities.
The three traveled with a fourth man, 19-year-old Hamza Ahmed, to New York by bus last November, intending to go to Syria. All four were prevented from boarding a flight to Istanbul.
