A leader of the Islamic extremist group al-Shabab, who has a $3m bounty on his head, has surrendered in Somalia, according to intelligence sources.

US special forces captured a Libyan al-Qaeda leader linked to the 1998 bombings of two American embassies in Africa, seizing him outside his Tripoli home and whisking him out of the country.

FBI experts have begun fingerprint, DNA and forensic analysis to help identify victims and the gunmen who attacked a Kenya shopping centre, killing more than 60 people.

American extremist Omar Hammami, who was reported killed in Somalia after he fell out with the al-Shabaab rebel group’s top commander, switched a mundane life in Alabama for a spot in the global jihad, with a $5m (€3.75m) bounty on his head from the US.
