What methods does Al-Qaeda use?

Answer 1

Al-Qaeda have many methods they use to try and get their point across, including hijacking, bombing and suicide bombing. These methods are very effective (take a look at 9/11) so they will probably keep using them for the near future.

Answer 2

Terrorists are all different and use different methods. Most of the current Muslim terrorists will apparently stop at nothing, including blowing up buses and stores full of innocent people and brutally murdering people they kidnap for cruel executions. People who commit these atrocities are beyond understanding and the free world has to use every possible means to defeat them.
