The American Secretary of State, Mrs. Hillary Clinton, has described the death of the head of Al Qaeda in East Africa Fazal Abdullah Mohammed as a significant blow to the organisation. Mrs. Clinton said it was a just end for a terrorist who brought so much of terror and pain to so many innocents.A report says, Fazal Abdullah Mohammad was believed to be the leader of Al Qaeda in East Africa. The US had a five million dollar bounty on his head and had been hunting him without success for years.The Somali Government said he was killed after a chance encounter in Mogadishu. It says the DNA tests proved conclusively that Fazal Abdullah Mohammad was killed. But the Islamist Al-Shabab said reports of his killing are untrue. The US wanted him in connection with the 1998 bombings of the American Embassies in Nairobi and Dar-es-Salaam. More than 200 people were killed, most of them Kenyans and Tanzanians. He was also accused of carrying out the 2002 twin attacks on Israeli targets on the Kenyan coast.
