"Iraq has a plan to... transfer all Iraqis" from the Al-Hol camp to another in Iraq that still requires significant work and support from international organisations to accommodate arrivals, Araji said.

But "the only and main obstacle is halting aid to organisations, and Iraq cannot resolve this issue alone".

Kurdish-run camps and prisons in northeastern Syria still hold about 56,000 displaced people, many with alleged or perceived links to the Islamic State group (IS), more than five years after its territorial defeat in Syria.

International aid organisations dependent on foreign funding provide services for residents of the camps.

Projects in Iraq have also received hundreds of millions of dollars in US assistance in recent years, according to official figures.

After returning to office in January, however, US President Donald Trump ordered a 90-day freeze on all US foreign aid before slashing multi-year contracts by 92 percent last week.

Al-Hol is the largest Kurdish-run camp, with more than 40,000 detainees from 47 countries living in dire conditions.

According to authorities, more than 13,000 Iraqis have left Al-Hol since 2021, and around 16,000 remain.

"If the support to international organisations had not ceased, it would have been possible" to repatriate all Iraqis by the end of 2025, Araji said.

Araji, meanwhile, also urged Turkey and the Kurdistan Workers' Party (PKK) to advance a previously announced peace plan, and called on them to withdraw from Iraq.

The PKK maintains rear bases in the mountains of northern Iraq, where Turkish forces have also established numerous bases.

"We don't want either the PKK or the Turkish army on our land... Iraq wants everyone to withdraw," he added.

"Turkish forces are (in Iraq) because of the PKK's presence," and "Turkey has said more than once that it has no territorial ambitions in Iraq," Araji said.
