A Kenyan court found two men guilty on Wednesday for their part in aiding Al-Shabaab gunmen who attacked the Westgate mall in Nairobi in 2013, killing 67 people. A third man accused of the attack was acquitted.

After a trial that began in January 2014, Magistrate Francis Andayi found that Mohamed Ahmed Abdi and Hassan Hussein Mustafa conspired with and assisted the four attackers, who died in a siege claimed by the Somalia-based Al-Qaeda-aligned group.

The third accused, Liban Abdullahi Omar, was acquitted of all charges and immediately allowed to leave the dock.
