But, from the videos available, it seemed like the explosives had very limited radius, where even people standing next to the targets were not hit or even knocked over!
It's not about being knocked over; these explosions created shrapnel and that shrapnel created tons of injuries. We don't have numbers because nobody bothered to count, but these were still bombs. There was no way they were not going to harm hundreds if not thousands of innocent civilians.
Count the number of commas per period in your response in the OP.
