A widespread, week-long civil defense drill will begin on Sunday, starting at the weekly cabinet meeting with a briefing by the commander of the exercise, Deputy Defense Minister Matan Vilnai.
The operative part of the drill commences on Monday. It will include, among other scenarios, a simulated missile attack on civilian areas - some with chemical warheads.
Participating in the drill will be the Home Front Command, the national emergency authority, government ministries and emergency services.  
At 10 A.M. on Tuesday a siren will be sounded throughout the country and children from kindergarten up will practice emergency procedures. State employees are also expected to drill emergency procedures at their workplaces.
Immediately afterward, local governments will join the exercise, following instructions that will be distributed on the spot.
The exercise will continue throughout the week, with scenarios that include a simulated hazardous material spill in the Haifa Bay, the rescue of survivors from a collapsed building in the Meron and Nazareth areas and the firing of ground-to-ground missiles equipped with chemical warheads.
During the exercise, Prime Minister Ehud Olmert and Defense Minister Ehud Barak are to conduct situation reviews and to make decisions based on the various scenarios as they unfold.
