The US Department of Justice says it has extradited four more US nationals accused of supporting ISIS in Kurdish-controlled areas of Syria, bringing Washington’s handover from Kurdish forces to an end. A DOJ statement says the US has extradited and returned 25 US nationals arrested in Iraq and Syria on ISIS membership or support charges, including 10 children. Trials for some of the returned ISIS members in the United States have already begun. The DOJ announcement came after Syrian Kurdish forces arrested the four US nationals on charges of supporting or belonging to the ISIS terrorist group. According to Stars and Stripes, the four were described as the last ISIS members Washington took over from Kurdish forces. The US also urged European countries to hand over ISIS members to Syrian Kurdish authorities. Kurdish forces have said they cannot manage around 10,000 ISIS fighters and about 70,000 of their family members, while the Kurdish Autonomous Administration has asked 54 foreign countries to extradite ISIS members. Some other US ISIS members are still in Iraq or Syria, but it is not known whether Syrian Kurdish forces detained them.
