Islamic State insurgency in Tunisia

The Islamic State Insurgency in Tunisia referred to the low–level militant and terror activity of the Islamic State branch in Tunisia from 2015 to 2022. The activity of the Islamic State (IS) in Tunisia began in June 2015, with the Sousse attacks, though an earlier terror incident in Bardo Museum in March 2015 was claimed by ISIL, while the Tunisian government blamed Okba Ibn Nafaa Brigade for the attack. Following massive border clashes near Ben Guerdane in March 2016, the activity of the IS group was described as an armed insurgency, switching from previous tactics of sporadic suicide attacks to attempts to gain territorial control. The armed insurgency was suppressed in 2022.

Rise of the Islamists
Since the death of Antar Zouabri the leader of the pro-al-Qaeda group called Armed Islamic Group of Algeria (GIA) which led an end of the Algerian Civil War in February 2002. The Islamist groups, like GIA and Salafist Group for Preaching and Combat (GSPC), continued the fight in their own insurgency in Algeria. In the meanwhile, on 11April 2002 a suspected al-Qaeda deadly bombing attack was carried in the Algeria's neighbour country Tunisia, on the island of Djerba. Twenty-one people were killed and dozens were injured. A suspected Polish with a German citizenship called Christian Ganczarski was arrested and jailed for having connections with al-Qaeda and the attacker. In December 2006, two people were killed by Islamists and two others were arrested. On 3January 2007 clashes broke out in Soliman, Tunisia, between the Tunisian Police and a suspected Islamist armed group. Fourteen people were killed, including two members of the security force, and fifteen people were arrested. In late 2012, the Tunisian Army launched some operations against the Islamist rebels whom are active around the mountainous Algeria–Tunisia border. On 16July 2014, a deadly attack against the army left fifteen soldiers and one attacker dead. Eighteen others were wounded on the Algeria–Tunisia border.

Bardo Museum incident
On 18March 2015, three militants attacked the Bardo National Museum in the Tunisian capital city of Tunis, and took hostages. Twenty-one people, mostly European tourists, were killed at the scene, while an additional victim died ten days later. Around fifty others were injured. Two of the gunmen, Tunisian citizens Yassine Labidi and Saber Khachnaoui, were killed by police, while the third attacker managed to escape. Police treated the event as a terrorist attack. The Islamic State of Iraq and the Levant (ISIL) claimed responsibility for the attack, and threatened to commit further attacks. However, the Tunisian government blamed a local splinter group of Al-Qaeda in the Islamic Maghreb (AQIM), called the Okba Ibn Nafaa Brigade, for the attack. On28 March, nine members were killed in a police raid.

Foreign support to Tunisia
In February 2016, British Defence Secretary Michael Fallon announced that a Short Term Training Team of around 20 soldiers from the 4th Infantry Brigade had deployed to Tunisia to help train Tunisian forces in countering illegal cross-border movement from Libya. The training involved both classroom and practical exercises, helping to improve the 1st Tunisian Brigade border security capability. The deployment followed on from what Fallon stated as "a previous tranche of border security training with the 1st Tunisian Brigade Headquarters at the end of last year."

In June 2016, Defence Secretary Fallon announced that the UK military support in counter-IED training would be extended for an additional year to help Tunisian Security Forces reach international standards of capability and achieve self-sufficiency in training. The British team in the country comprising counter-IED and training specialists, as part of a multinational team, deployed in March 2015 and had been "instrumental" in bringing structure and clarity to training at the Explosive Ordnance Device School in the country, helping transform it into a specialist centre offering 14 different courses. Separately, it was also announced that in the summer of that year, the UK would provide three specialist month-long training courses to the Tunisia National Guard Commando, to help them deal with internal and external threats. The decision stemmed from a request made by the National Guard, will focus on medical training, small boat handling and security operations training and would create a cadre of instructors to further cascade training within the National Guard.

In October 2016, Defence Secretary Fallon announced that a Short Term Training Team of around 40 soldiers from the 4th Infantry Brigade deployed to the country to train 200 Tunisian troops in theoretical and practical exercises on Operational Planning, Intelligence and Surveillance and mobile patrolling, which would help Tunisia counter illegal cross-border movement, particularly from Libya.
