Sunday morning gunfire soon erupted as the attackers began shooting staff and shoppers. Kenyan authorities identified who the attackers only after Islamic extremists claimed the attack. The people who are responsible for the attack are part of Somalia's radical rebel group al-Shabab.
Two Kenyan security forces were wounded in the gunfire and immediately carried out of the shopping mall. The main targets of the attack were non-Muslims. Besides Kenyans casualties, in the confirmed dead there were also foreigners including Canadians and French.
