AZRAQ REFUGEE CAMP, Jordan (AP) — International aid groups say about 8,500 Syrians are still locked up behind barbed wire in a no-go section of Jordan's second-largest refugee camp, despite initial assurances in 2016 the arrangement is temporary.

The Jordan INGO Forum, an alliance of 60 groups, asked Jordan to expedite security screenings of those held in Azraq camp's "Village 5," saying that at the current pace this would take until October 2020.

The alliance asked Jordan in a recent report to lift movement restrictions on Syrians in camps.

Coordinator Yannick Martin said on Tuesday that Jordan has done much to host Syrian refugees, but that "a frank dialogue needs to take place" on movement restrictions.

Jordan says its security is paramount, that it shoulders a heavy refugee burden and that its security vetting is exemplary.
