A senior member belonging to the Somalian terror group Al-Shabaab, Ahmed Ismail Ali, has been executed, officials here said.
Ali was captured last week by Somalian government troops in the Somalia-Kenya border town of Burdhube, Xinhua reported Thursday.
He was accused of being behind the killing of 28 Kenyans, many of whom were teachers, in the border town of Mandera.
The official did not say when Ali was executed.
In December 2014, Al-Shabaab militants ambushed a Nairobi-bound bus and killed 28 passengers.
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.
The execution came a month after the surrender of former Al-Shabaab intelligence leader Zakariye Ismail Ahmed Hersi who is now being held by authorities.
