US Special Forces assassinated a leading Islamic militant on Monday during a daytime raid in Somalia. Four US helicopter gunships bombed a pair of trucks carrying leaders of the militant group Shabab. US officials said six people died, including Saleh Ali Saleh Nabhan, who has been described as the ringleader of an al-Qaeda cell in Kenya. US forces have been hunting him for years. Nabhan had been wanted for questioning in connection with a deadly car bombing of a beach resort in Kenya in 2002 and the near simultaneous attempt to shoot down an Israeli airliner.
