According to The Associated Press, unidentified gunmen who threw fragmentation grenades and fired indiscriminately on non-Muslim at an upscale mall in Nairobi on Saturday (September 21) killed at least ten people in an attack that was hosting a children's day event.

A local hospital was overwhelmed with the number of wounded being brought in hours after the attack, so they had to divert them to a second medical facility.

When they first entered the Westlands Mall, located in an area frequented by expatriates and wealthy Kenyans, they ordered all Muslims to stand up and leave safely.

COMMENT: AP journalists at the scene reported that they observed the bodies of at least ten people, not to mention dozens of injured victims.

Somali's rebel group al-Shabab vowed in late 2011 to carry out a large-scale attack in Nairobi in retaliation for Kenya's sending of troops into Somalia to fight the Islamic insurgents.

No group has claimed responsibility for the attack.
