I was offered a cpt position out there on a bravo, turned it down not enough money but the problems of living there even for a 2 week rotation was a headache. Last may 2011 a British and Italian where kidnapped and later killed this year in March 2012. They even offered me security but not worth it, so i declined the job, dont know who got it but good luck to them.
Maybe bizjetjock look at latest info here

Good luck
