Islamist Group Al Shabaab attacks Kenya-US military base

Islamist group al Shabaab on Sunday attacked a military base in Lamu county in Kenya that is used by both U.S. and Kenyan forces. 

The attack comes nearly a year after al Shabaab launched a deadly suicide attack on the upscale 14 Riverside complex in the Kenyan capital Nairobi, killing 21 people.

Harakat al-Shabaab al-Mujahideen, more commonly known as al-Shabaab, is a jihadist fundamentalist group based in East Africa.
