A car bomb targeting Turkish contractors exploded in Afgoye, northwest of Mogadishu, wounding at least six people, police said.
It was not known who carried out the attack but residents and police said al Shabaab fighters tried to attack Afgoye on Friday and were repulsed.
“A speeding suicide car bomb rammed into where the Turkish engineers and Somali police were having lunch,” police officer Nur Ali told Reuters from Afgoye.
“So far we know three Turkish engineers and their translator were injured. Two policemen were injured in the blast,” Ali said when asked about casualties.
Turkey’s state-owned Anadolu news agency said four Turks, employees of a construction firm, were wounded in the attack and were being treated in hospital, citing information from the Turkish embassy in Mogadishu.
The al Qaeda-linked militant group claimed responsibility for past attacks in its campaign to overturn Somalia’s UN-backed government.
“We heard a huge blast and saw clouds of smoke in the air. Before the blast, several Turkish engineers and armed Somali police were at the scene,” Farah Abdullahi, a shopkeeper, told Reuters from Afgoye.
“We see casualties but do not know if they are dead or injured.”
Turkish engineers are helping with road construction in Somalia. A group of engineers was hit in December by a blast at a checkpoint in Mogadishu that killed at least 90 people.
