Tunisia says suicide bomber carried out bus attack claimed by Islamic State

Tunisian authorities said on Wednesday a suicide bomber wearing a vest packed with plastic explosive blew up a presidential guard bus a day earlier, killing at least 12 troops in an attack claimed by Islamic State militants. "This attack is an evolution in the behaviour of the terrorists, this time they attacked a symbol of the state and in the heart of the capital," Prime Minister Habib Essid told reporters after an emergency security meeting. An Interior Ministry statement said 12 guards died in the blast of Semtex explosive located in a belt the bomber was wearing. The explosives had been traced to Libya, it said. Another body at the scene was probably that of the bomber.
Security officials said the bomber detonated his blast just as presidential guards were boarding a bus on Mohamed V Avenue to travel to the presidential palace for duty.
