Ordinarily I ignore most posts begging for funding, but having heard what is happening to Iraqi doctors (kidnapping and extortion from the looks of things), I sincerely hope you are able to find some funding and get to safety.
As you already have a medical degree you may be better of getting a research assistants post in a medical research facility.
I wouldnt normally recommend doing a PhD, but in your case you hell you will at least be safe. You may wish to look for a funded studentship (your MBBS and experience will put you at considerable advantage to most other applicants).
It takes a post like this to make me realise that although I am struggling on crappy temp work and fruitlessly searching for academic employment, things could be infinitely worse.
Good luck.
