Garissa Shooting Mastermind Killed

Senior Al Shabaab officer Mohamed Mohamud alias Sheik Dulayadayn addresses a news conference during clashes between Ismalist fighting and Somali government in Somalia's capital Mogadishu this file picture taken on January 1, 2011. The death toll in an assault by Somali militants on a Kenyan university is likely to climb above 147, a government source and media said on April 3, 2015, as anger grew among local residents over what they say was a government failure to prevent bloodshed. Within hours of the attack, Kenya put up a 20 million shillings ($215,000) reward for the arrest of Mohamed Mohamud, a former Garissa teacher labeled "Most Wanted" in a government poster and linked by Kenyan media to two separate al Shabaab attacks in the neighboring Mandera region last year.
