I'm not aware of the specifics of this reality. I can say one thing, though, because of the lack of fuel everywhere, everybody is forced to buy it on the black market, including Global Affairs Canada staff. This is truly a major crisis.
How far does the influence of gangs extend? According to NGOs, they aren't working with gangs. However, there is certainly a black market for basic necessities, such as fuel, which is the only source of energy. It's not an easy situation.
