A suicide bomber was killed, and seven civilians wounded, when a vehicle exploded near a checkpoint outside the presidential palace in Somalia’s capital, Mogadishu.
Police spokesman Sadiq Ali Adan said the driver defied orders to stop and police opened fire as passersby ran for their lives.
He said more than a dozen vehicles were destroyed in the blast.
This latest bombing occurred as Somali politicians argue over how to hold a national election.
The vote had been scheduled for Feb. 8, and some argue that President Mohamed Abdullahi Mohamed, who seeks a second four-year term, has overstayed his mandate.
More talks on the election crisis are set for Monday.
The al-Qaida-linked al-Shabab extremist group based in Somalia often targets high-profile areas of Mogadishu. It has threatened to attack the polls.
