At least 11 people were believed killed when a car bomb detonated outside of a busy shopping center in Mogadishu, Somalia on Monday. Another ten people were injured in the blast, which is believed to be the work of al-Shabaab, an Islamic extremist group currently operating in the region. However, no group has yet claimed responsibility. According to a report from Al Jazeera, the bombing also caused a nearby building to collapse, which added to the casualty count.

“Several dead people were removed from a wrecked building at the blast scene. So far, the death toll is 11 civilians and 10 others injured,” said Mohamed Hussein, a Somalian police officer currently working the scene while speaking to Reuters.

“I saw the dead bodies of four people recovered from the debris of a collapsed building and three others were strewn dead outside after the blast had blown them,” said  Munira Abdukadir, an eyewitness to Monday’s attack while speaking to Al Jazeera.

Al-Shabaab has a long history of attacking Somalian government facilities, as well as civilian targets. According to Reuters, al-Shabaab is loosely associated with al-Qaeda and wants to seize control of the government in order to implement sharia law. The group’s campaign of violence is not limited to Somalia. Last month, the terrorist organization killed 21 people in a hotel in Nairobi, Kenya.
