Israeli military, police, Shin Bet and special counterterrorism units early Monday staged their largest ever counter-terror exercise which simulated massive al Qaeda attacks coming in through Syria and Egypt against strategic targets and army bases. The scenario depicted scores of Israeli dead and hundreds injured, as well as the capture of hotels with large numbers of people held hostage. The exercise was planned secretly. Some of the units taking part received no advance warning of their roles until they reached the “targeted locations.” A senior army officer rated the exercise “satisfactory.”
