A Tunisian street vendor gives jasmine flowers to tourists in the village of Sidi Bou Said, some 20 kilometers northeast of Tunis, on March 22, 2015, four days after an attack on the Bardo National Museum in the Tunisian capital. Tunisia's President Beji Caid Essebsi promised to wage a "merciless war against terrorism" after gunmen killed at least 17 foreign tourists and two Tunisians in a daylight attack in the birthplace of the Arab Spring.
