It will be very dark and they are hiding so you won't just be able to see them.

Also when they are running, it is again very dark, plus there will be panic, plus there will be a big cloud of dust from the explosion which is too thick to see through. It will be hard to hit with a throwing knive if you have no idea were your target is.
