Tunisian authorities have identified a Tunisian national as the suicide bomber from Tuesday's bus attack, which killed 12 presidential guards, the interior ministry said on Thursday, 26 November.
The Islamic State has claimed the bombing, the third major militant attack in Tunisia this year following assaults on a beach resort at Sousse and the Bardo museum in the capital, targeted foreign visitors.
Interior Minister Najem Gharselli named Tuesday's attacker as Houssem Abdelli, 28, a street seller who lived near Ettadhamen, one of the poorer neighbourhoods of Tunis. She gave no details of any ties he might have had to Islamist militant groups.
The authorities said 12 guards died in the blast of Semtex explosive located in a belt the bomber was wearing when he detonated it stepping on the bus on Mohamed V Avenue, one of the capital's main streets.
As compared to neighbours Libya and Egypt, Tunisia has largely been a haven of stability since 2011, when an uprising ousted autocrat Zine Abidine Ben Ali. It has formulated a new constitution, held free elections and established a political framework that has found room for both secular and Islamist parties.
But, Islamist militants now pose a serious challenge for a country heavily reliant on tourism for its hard currency.
Several thousands of Tunisians are fighting with Islamic State and other groups in Iraq and Syria, and the gunmen in the Sousse and Bardo Museum attacks were all trained at Jihadist camps in Libya.
