Two explosions rocked Tunis on 27 June, targeting security positions. One blast struck a security vehicle in a busy area of the capital, while the second targeted a police building. A number of police personnel and three civilians were killed. Tunisia has been battling militant groups operating in remote areas near the border with Algeria since an uprising overthrew autocratic leader Zine Abidine Ben Ali in 2011. Since the revolution, dozens of the security forces and 59 foreign tourists have been killed. After an IS-claimed suicide bombing killed twelve presidential guards in 2015, Tunisia has been under a state of emergency. Tunisians made up a large component of the foreign fighters in IS, while the porous border with neighbouring Libya has also aided militants. Spiritually Tunisians are being exposed to the truth of the gospel as they interact with believers on social media sites and search Christian websites.
