We have al-Qa'eda on the run,' President Bush was reported to have said in April. In May, al-Qa'eda and its associated groups masterminded a week of bombings which left more than 100 people dead. It looked like a deliberate riposte to the President's triumphant optimism. There were two explosions in Chechnya on 12 May, which killed 59 people and injured 200. There were three in Morocco on 16 May; the toll was 27 dead and more than 100 injured, not counting the blowing to smithereens of the 12 suicide bombers who had jointly detonated the bombs. And in the same week, there were the bombs in Riyadh, Saudi Arabia, which killed 34 people, as well as the 19 bombs which exploded in Shell petrol stations in Pakistan.
