One of the strategy papers said al Qaida was planning a combination of smaller and larger attacks in order to "drive the enemy to desperation." According to other documents, the terrorist group was planning to take hostages and then kill them. They also described plans to use poisons and disguises.
Al Qaida reportedly expected that spreading fear among the population and the implementation of more repressive tactics by authorities would result in the marginalisation of Muslim communities, which would in turn bring in more recruits for the Jihad.(source)
