16 February 2015 :

Somali Government announced that Ahmed Ismail Ali, a senior Al-Shabaab leader in southern region of Gedo, was executed after being convicted by a military court.
Ali was captured previous week by Somalian government troops in Somalia-Kenya border town of Burdhube. He was accused of being behind the killing of 28 Kenyans, many of whom were teachers, in the border town of Mandera.
In December 2014, Al-Shabaab fighters ambushed a Nairobi-bound bus and killed 28 Kenyan non-Muslim passengers and later massacred 36 quarry workers in Mandera County.
Sources said Ahmed Ismail was also among the militants accused of masterminding the 2013 Nairobi Westgate shopping mall attack in which 68 people were killed and over 200 injured.
