With internet being practically shut down by the “government” except for a very few individuals connected to the regime, my family in Iran has no means to get the alerts about the areas that are getting or gonna get bombed or have been bombed and maybe able to the non existent shelters.
Does your family work at military installations?
Is the U.S. (or other) government posting somewhere publicly that they're going to be bombing some military installation in X minutes/hours?
