A car bomb exploded close to the presidential palace in Somalia's capital Mogadishu on Monday, killing at least 7 people, reported government spokesman.
No one has claimed the responsibility for the attack, but the militant group Al Shabab is believed to be behind it, since the group has been trying to overthrow President Hassan Sheikh Mohamud.
The Al Qaeda-affilliated Al Shabab, which targeted the palace before, is known to break into designated targets with cars driven by suicide bombers and more attacks are generally followed by armed militants on foot.
However, this was not the case for Monday's attack as it only involved a suicide car bomb, said officials.
"At least seven people were killed and more than ten injured" in the explosion, said Abdifatah Halane, government spokesman for the Banadir region which includes the capital.
"The majority of the dead and injured were civilians," he added.
A Somali security official, Ahmet Dahir, said the car exploded near the safety zone of the entrance to Villa Somalia. However, noted that "their target is not clear".
"The explosion occurred between the main entrance of (Villa Somalia) and a nearby hotel," said a witness named Ali Ahmed.
As Al Shabab militants have been driven out of many regions they once controlled in Somalia, including Mogadishu, they have carried out more frequent violent attacks targeting government officials and civilians.
They are fighting to bring down the internationally-backed government in Mogadishu, which is protected by 22,000 African Union AMISOM troops from Burundi, Djibouti, Ethiopia, Kenya and Uganda.
