Sailing mentioned one, but there's others that are at the very least a highly elevated risk based on current events and status of nefarious elements. I'll leave it to you to check out the route map and decide for yourself. I've heard of crews robbed and van drivers shaken down by "cops" more than a few times in one of the biggest international cities we layover in, all because we're trying to get our contractual "downtown or downtown like" overnight on. Not worth it IMO, but in any case there are several cities where its more a matter of when than if when you take an honest look at the reality of how bad things there really are or are becoming.
