TUNIS, Tunisia — A suicide bomber and a teenager carrying a backpack loaded with explosives attacked two sites popular with tourists Wednesday, raising fears that Tunisia’s Islamist extremists may be adopting more violent tactics.
No one was killed besides the suicide bomber, but with the Ministry of Interior saying both men belonged to the same extremist group, the attacks could signal the adoption of more deadly tactics by Tunisia’s Islamist extremists, including ones aimed at tourists.
The extremists have experienced a resurgence since Tunisia kicked off the Arab Spring in 2011 by overthrowing its secular dictatorship.
In what may have been the first suicide attack in Tunisia, hotel security guards stopped the bomber from entering the Riadh Palm hotel in Sousse, a city 90 miles south of the capital, Tunis, then chased him to a beach where he blew himself up, the Interior Ministry said.
In the foiled attack in nearby Monastir, an 18-year-old followed a group of tourists into the mausoleum of modern Tunisia’s founder, Habib Bourguiba, carrying a backpack full of TNT. He attempted to distract security by tossing a firework before being subdued, said Hicham Gharbi, a spokesman for the presidential guard, which patrols the site.
‘‘He will be questioned to learn his motives and those who ordered the attack,’’ Gharbi told local radio.
