What does it refer to? As a pronoun, does it refer to the whole situation or the previous sentence?
The images are gut-wrenching. In one video, a man tries to revive a child, a boy perhaps three or four years old, by pouring water over his face, rubbing him, attempting a futile resuscitation. The boy is pale and limp and appears to have died. Around him there are more bodies in similar states of death or near-death, prostrate on a floor. Men move around with the kinetic energy of those overwhelmed by a catastrophe and lacking the knowledge and the tools to save the victims. Oddly, there is no blood. It is as if everyone has drowned.
