A Somali police official says a car bomb has killed at least seven people and wounded 10 others at a popular cafe in the capital.

Mohammed Hussein, a senior police official, said Sunday the blast struck the Aroma cafe in Mogadishu. No group has claimed responsibility for the attack but suspicion has fallen on the al-Qaida-linked al-Shabab militants who have vowed to avenge the death of their leader, Ahmed Abdi Godane, who was killed in early September in a U.S. airstrike. Godane has been replaced by Ahmed Omar, also known as Abu Ubeid.

Al-Shabab has continued to carry out attacks on Somalia's capital despite being pushed out of Mogadishu by African Union forces supporting Somalia's weak U.N.-backed government in August 2011.
