Huge explosion at gas station injures four

By a traffic-choked intersection in Makhachkla, Dagestan, a pump smokes ominously on a gas station forecourt. Nearby drivers peel away from it as fast as they can, and a local with a good vantage point starts filming. By the time it goes up, few are in the area--and yet the size of the blast resulted in at least four injuries, according to reports.
