Major al-Shabab attacks targeting Kenya

The al-Shabab armed group is based in Somalia fighting to topple the Western-backed Somali government and wants to impose a strict version of Islamic law in the Horn of Africa country.

The armed group has carried out several attacks in neighbouring countries, including Kenya, since Nairobi launched a military operation inside Somalia in 2011.

The group used to control most parts of south and central Somalia, but since 2010, the fighters have been removed from most major towns and cities, as the US military and a 20,000-strong African Union peacekeeping mission boosted the Somali forces.
