Former teacher is alleged to be behind attack
The man alleged to be behind the terrorist attack on Garissa University is a former teacher at an Islamic school who rose to become one of al-Shabaab's most senior lieutenants.
Dulyadin Gamadhere, pictured above, who goes by several other names including Mohammed Kuno, is said to come from a family of sympathisers of the militant Somalia-based group.
He is now the subject of a bounty of five million Kenyan shillings (£36,000) for his suspected masterminding of the attack on the university.
According to a report on Nairobi's 'Star' newspaper website, he worked as a teacher at a religious school under the name of Sheikh Mahamad Afte. But he increasingly took a hard line and later joined al-Shabaab when it was formed in 2006.
