Det som trolig var en selvmordsbomber sprengte seg selv og tok med seg 12 av presidentens livvakter i døden i Tunis tirsdag. 17 ble såret.

Eksplosjonen skjedde dagen før president Beji Caid Essebsi skulle dra til Europa. Turen er nå avlyst.

Borgerinitiativ fikk Fredsprisen i år, for sitt arbeid for å skape sivil dialog. Men sporene har tydelig pekt mot mer terror.

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.

Security sources said the guards were boarding the bus to be taken to the presidential place on the outskirts of the city when the explosion hit. One presidential source said it was likely that a bomber had detonated his explosive belt inside.

«I was on Mohamed V, just getting ready to get into my car, when there was a huge explosion. I saw the bus blow up. There were bodies and blood everywhere,» said Bassem Trifi, a witness.

President Beji Caid Essebsi canceled a trip to Europe he had planned for Wednesday.
