“On 8 April [2003], bin Laden issued a tape urging people to take up arms and join a jihad against the Muslim governments which supported the US invasion–namely Pakistan, Afghanistan, Bahrain, Kuwait and Saudi Arabia. He also addressed those already carrying out guerrilla operations inside Iraq to start a campaign of suicide bombing: ‘Do not be afraid of their tanks and armoured personnel carriers,’ he said, ‘these are artificial things. If you start suicide attacks you will see the fear of the Americans all over the world.’ “
