U.S. drone strikes are believed to have killed the leader of the Somali terrorist group al-Shabab, who ordered the massacre at a Kenyan shopping mall last year that killed 67 people. U.S. Intelligence officials believe Ahmed Abdi Godane was traveling in a two-car convoy Monday night near al-Shabab's main base in Barawe when American drone aircraft hit the vehicles with missiles. Six people were killed in the attack and Somali authorities say they think Godane is among the dead - though the Pentagon said it is still awaiting confirmation. Godane, also known as Mukhtar Abu Zubeyr, is al-Shabab's spiritual leader under whose direction the Somali militants forged an alliance with al-Qaida and became the most high-profile terrorist group in Africa.
