MOGADISHU, Feb. 9 (Xinhua) -- At least four people were killed and seven others injured in an explosion at a restaurant in northeast Somalia's commercial city of Bosaso on Wednesday afternoon.
A Puntland police officer told state-run Radio Mogadishu that the bomber struck in front of a restaurant in Bosasso's Al Macruuf shopping center.
The motive of the latest attack in Puntland State has not been established.
Locals said security forces have launched a major manhunt for the perpetrators of the latest explosion in Bosaso town which has been beset by a series of landmine and suicide bombings including assassinations in the recent past.
No group has claimed responsibility for the blast but al-Qaida allied terror group, al-Shabab and the Islamic States (ISIS) have staged such attacks in the past in Bosaso and elsewhere in Puntland State.
The so-called ISIS wing in Somalia has its main base in the Puntland region and has occasionally clashed with Puntland forces and al-Shabab. ■
