Mogadishu , Somalia ( CNN ) -- A former government official was among 10 people killed in a bombing Saturday in Somalia 's capital , with Al-Shabaab -- the Islamist militant group that 's long been tied to violence in the region -- claiming responsibility for the attack . The slain official , Abdikafi Holowle Osman , was a former Benadir regional administrative secretary and an active campaigner against Al-Shabaab . He died when a bomb went off as he was driving in KM4 , a busy junction in Mogadishu , police said . Police Col. Kamal Farah said the explosive device was attached to Osman 's when it went off shortly after noon ( 5 a.m . ET ) . Three security guards and six civilians who were nearby also died in the blast , according to Farah . Hospital sources said at least eight people injured were being treated at Media Hospital . Separately , there were no injuries after a device attached to the car of Somali lawmaker Abdullah Ahmed exploded outside a hotel near the port , close to the heavily fortified government district . The prime minister 's office indicated that a Somali citizen had alerted authorities that the car had been rigged with explosives . In a statement , Al-Shabaab claimed responsibility for both Saturday attacks in the eastern African nation 's capital . Al-Shabaab official Ali Mohamed Hussein accused Osman of working with `` foreign spy agencies '' based southwest of Mogadishu . Al-Shabaab is seeking to turn Somalia into a fundamentalist Islamic state , though it has carried out attacks in other African countries as well . A prime example of the latter was last September 's attack on Nairobi 's Westgate Mall , which ended with at least 67 dead . Somalia 's Prime Minister Abdiweli Sheikh Ahmed issued a statement Saturday , sending condolences to the families of those killed in the latest violence . `` Shedding the blood of innocent civilians has no basis in our Islamic religion or in Somali culture , '' he said . Omar Nor reported from Mogadishu and CNN 's Greg Botelho wrote this story from Atlanta . CNN 's Leslie Holland and Samira Said contributed to this report .
