At least 12 people were killed on Tuesday after an explosion tore through a bus full of Tunisian presidential guards in an attack one source said was probably carried out by a bomber detonating his explosives in the vehicle.
Ambulances rushed wounded from the scene and security forces closed off streets around Mohamed V Avenue, one of the major streets in the capital Tunis and where the charred wreckage of the bus lay not far from the interior ministry.
It is the third major attack to strike Tunisia this year after a militant killed 38 foreigners at a beach hotel in June and gunmen killed 21 tourists at the Bardo Museum in Tunis in March. Islamic State claimed both those attacks.
