At least four people were killed and 10 others wounded when a car rammed into a busy restaurant and exploded in the Somali capital Mogadishu, local sources told Al Jazeera.

The blast on Tuesday targeted the Bonoodo restaurant located near the city's Central Hotel, which was the scene of a deadly attack in February.

There was no immediate claim of responsibility for Tuesday's attack, but Abdirizak Omar, Somalia's interior minister, wrote on his official Twitter account that seven al-Shabab fighters were killed by the government forces at the site.
