Professor Alice Hills, lka @ Leeds University, has written extensively on policing and may have covered the region. She is now @ Durham and her bio indicates a broad interest and writing, but on Africa mainly:https://www.dur.ac.uk/sgia/profiles/?id=11424

Joana Cook @ Kings War Studies has an interest in policing as part of CT in the region, her focus was the Yemen and lately Saudi Arabia. I know her so will alert her.. Her bio:http://www.kcl.ac.uk/sspp/department...phd/jcook.aspx

There is a former UK policing plus adviser @ RUSI, who served in Iraq and I will connect you.

It maybe worth looking at SSR material and focus on the region.

The UK, along with others, have offered places for Middle Eastern police leaders at staff colleges. Not sure if they publish anything though.

There was a UK police team in Iraq advising and IIRC some have published articles.
