Iraq’s foreign minister said Friday that more than 5,000 detainees affiliated with the Islamic State group have been transferred from Syrian prisons to Iraq, as Baghdad negotiates with other countries to repatriate their nationals and calls for increased financial support to manage the influx.

Speaking to Reuters on the sidelines of the Munich Security Conference, Foreign Minister Fuad Hussein said additional transfers are ongoing and warned of a recent uptick in Islamic State activity inside Syria, underscoring persistent regional security concerns.

Ahmed Laibi, spokesperson for Iraq’s Justice Ministry, told the state-run Iraqi News Agency that 5,064 detainees linked to the extremist group — also known as ISIS — have been moved to Iraq following the completion of legal procedures. The group includes more than 270 Iraqis, over 3,000 Syrians and other foreign nationals, he said.

All are being held in a single detention facility and are undergoing investigation and trial under Iraqi law, Laibi added.

Iraq agreed to detain the suspects at the request of the Global Coalition Against Daesh, of which Baghdad is a key member, officials said.

On Wednesday, the Washington-based outlet Al-Monitor reported that 66 Islamic State fighters of Turkish origin were transferred from prisons in Hasakah province in northeastern Syria to coalition forces for relocation to Iraqi territory. A senior Kurdish official cited by the outlet dismissed claims that thousands of Turkish ISIS detainees were being held, saying their identities are known to coalition authorities but cannot be disclosed for security reasons.

Developments are also unfolding at the Al-Hol camp in northeastern Syria, which once housed around 24,000 people, mostly women and children linked to Islamic State suspects. Aid workers say fewer than 20 foreign families remain in the camp’s foreigners’ section after Syrian government forces took control from Kurdish authorities. Some residents have reportedly relocated, while others may have fled during the transition.

Hussein said Iraq takes signals from the United States seriously but stressed that political matters — including the possible return of former Prime Minister Nouri al-Maliki — are internal Iraqi issues.
