UPDATE to original post with more recent claims:

In light of the recent Islamic State claimed attack in Tunisia and confusion by some on Twitter on when the last IS attack was in Tunisia I thought it would be useful to write up a post that helps clarify the issue and shows all of the IS attacks that have occurred in Tunisia. These are based on claims of responsibility from the Islamic State’s Tunis Media Office, Amaq News Agency, al-Naba’ Newsletter, and al-Bayan Radio, Jund al-Khilafa in Tunisia’s Ajnad al-Khilafah bi-Ifriqiya Media Foundation as well as Ifriqiyya Media. The latter was used prior to IS officially claiming responsibility. The language below is how IS/JKT claimed responsibility. Lastly, it should be noted that the claimed attacks do not necessarily reflect the actual events, i.e. the information in the claims.

The following attacks were claimed in an Islamic State video by the French-Tunisian Bubakr al-Hakim, though the attacks occurred when al-Hakim was allegedly still in Ansar al-Sharia in Tunisia. It is possible though he broke from them by this time since he disagreed with the dawa-first approach of Abu ‘Iyadh al-Tunisi.
