Official:Al-Shabab fighters pledge allegiance to ISIS

The splinter group is operating around the Somali border in Kenya's north, and has carried out at least two attacks in the last two weeks, killing one soldier and two civilians in Mandera County.
Among those who have joined the pro-ISIS faction of al-Shabab is Mohamed Kuno, alias Gamadhere, who is wanted for the April 2 attack by al-Shabab gunmen on a Kenya's Garissa University in the country's east, in which 148 people were killed, Boinnet said.
