MOGADISHU, Somalia 

At least five people were killed and 10 others wounded in suspected suicide bombing in the Somali capital of Mogadishu on Wednesday.

The attack took place near a security checkpoint on the busy Mogadishu-Afgoye highway.

Nour Abdirahman, a security official in Mogadishu, told Anadolu that the attack occurred during morning rush hours and the police believe it to be a suicide blast.

Investigation was initiated to determine the cause of the explosion, he added.

The Al-Shabaab terrorist group, which has been fighting for nearly two decades to topple Somalia's central government, claimed responsibility for the attack.
