There are two different kinds of sirens in Israel. An urgent rising and falling sound warns of an attack and is the signal to flee to the nearest bomb shelter or safe room. A mournful steady sound is for remembrance.
last week, at 5 in the morning, the people of Mishmoret, a small moshav located near Kfar Saba, were woken by a siren as a Gaza rocket was about to land in their community. No one expected this. There was no Iron Dome protecting this community. Some of the residents of Mishmoret were not even sure what they were hearing and many did not have safe rooms in their homes. They were not prepared.
