Plot hole: In one of the scenes where Jones and Del Toro are fighting hand to hand, Del Toro's knife is knocked into the bushes. They continue to fight until a point where Del Toro has gained the upper hand. Del Toro is on top of Jones, who is almost unconscious. Instead of finishing Jones off, Del Toro looks around for his knife. This doesn't make sense. Del Toro is a trained killer. He doesn't need a knife to kill Jones.
Plot hole: After the team takes care of the ethnic cleansers, there is a flat-bed lorry with a belt-fed weapon just sitting there. Since the cleansers came in from somewhere ahead of the team, why not load the refugees onto the truck and head out? If nothing else, it would increase their lead over the pursuers.
