At least 11 people were killed and 14 were injured Tuesday after an explosion in Tunis damaged a bus carrying members of the president’s security guard, an official told CNN. President Beji Caid Essebsi was not near the explosion, officials said.
The blast occurred when the bus was parked in the Tunisian capital where guard members are usually picked up and dropped off, according to an official in the Tunisian Prime Minister’s office. The New York Times reported that it happened on Mohammad V Avenue near a clock tower.
It was not immediately clear whether the explosion was caused by an explosive fired at the bus or if it was caused by a bomb. Nor was it clear who was responsible for the explosion.
Tuesday’s attack was one of the first serious attacks on security forces that Tunisia has suffered in its capital since jihadists started a campaign of violence in 2011, though low-level attacks on forces and police officers have occurred across the country.
According to CNN, Tunisia has been regarded as a success story of the Arab Spring, the movement that has brought huge changes to the region. However, the North African nation did suffer an attack on the Bardo National Museum in March that killed 22 people and on a seaside hotel in June that killed 38 people. ISIS–the Islamist extremist group–claimed responsibility for both of the attacks.
In the wake of the attacks by the Islamic State in Lebanon, Beirut and Paris, Tunisian officials increased the capital’s security level 10 days ago. Authorities also deployed soldiers and police officers to patrol the city.
