"We bombed two al Shebab camps in the Gedo region," Kenyan army spokesman David Obonyo told AFP.

“The two targets were hit and taken out, the two camps are destroyed."

Past Friday Al Shabaab gunmen stormed Garissa University College killing at least 147 people on Thursday, in the worst attack on Kenyan soil.

The siege ended nearly 15 hours after the Somali group's gunmen shot their way into the University in a pre-dawn attack, sparing Muslim students and taking many Christians hostage.
