Air raid sirens sounded throughout Israel shortly after 10 AM as part of a nationwide drill for the educational system.
The IDF Homefront Command and the Education Ministry announced the drill ahead of time.
The Israel Police, Magen David Adom emergency services, the Israel Fire and Rescue Service, and local authorities are simulating their response to a real missile attack on the Israeli home front from multiple arenas simultaneously, that strikes when schools are in session.
State and local radio stations were to play an audio recording announcing the drill, while announcements on TV stations and internet sites provided details about the exercise.
Pupils in institutions of learning have received instructions on how to respond.
Home Front Command search and rescue teams were scheduled to rehearse rescue operations in six schools across the country.
The IDF Spokesman's Unit said the annual drill has been planned ahead of time for 2016.
