On Wednesday, gunmen stormed a museum in Tunis, Tunisia, killing 22 people and injuring at least 22 more. Tunisian security forces killed two attackers in the ensuing firefight, but three remained at large. No organization immediately claimed responsibility for the attack, but local groups affiliated with al Qaeda are active in the country, and the Center for Strategic and International Studies suspects that some cells have pledged allegiance to the Islamic State. Indeed, the Islamic State claimed responsibility the next day and promised more attacks in Tunisia. Tunisian authorities announced nine arrests on Thursday, claiming that four of the persons arrested were directly related to the attack. Foreign Policy reports that the attack threatens the last vestiges of the Arab Spring.
