This item from The Observer might help explain why the U.S. is having a few problems in rounding up its top suspects in the war on terror:

President General Pervez Musharraf of Pakistan told CNN that the US missile strike earlier this month, which killed 22 people near the border with Afghanistan, was a 'violation of sovereignty'. But he claimed that among the innocents killed in the drone attack was Midhat Mursi al-Sayid 'Umar - known as Abu Khabab - an al-Qaeda chemical weapons expert.

But US intelligence agencies who had been hunting Abu Khabab kept a little quiet after it was noticed last week that for a year and a half they had been appealing for the public's help in finding him by using a photograph of the wrong man on his wanted poster.

The Abu Khabab shown on a State Department Rewards for Justice website, with a $5 million bounty, was a photograph of radical London iman Abu Hamza. A CIA spokesman admitted a 'human error'.
