On February 23-24, 2014, three explosions were reported in Zanzibar. They occurred outside the Tanzania Assemblies of God Church, at the entrance of the Anglican Church compound and in a popular restaurant in Stone Town. Further attacks cannot be ruled out. Be vigilant in crowded places and monitor local media.
