Security concerns

The United States State Department
reported the Tunisian Islamic Front claimed credit for murdering four policemen, and had warned all foreigners to leave Tunisia:

In May the extremist Tunisian Islamic Front (FIT) issued a warning that all foreigners in Tunisia should leave, but it did not follow up with any concrete threats or attacks. The group also claimed responsibility for a number of operations in Tunisia, including the murders of four policemen. Tunisian authorities have not confirmed or denied the claims. There are allegations that the FIT is working in conjunction with the Algerian Armed Islamic Group (GIA), and that its members may be training in GIA camps. Several Tunisians were taken into custody in 1995 for alleged involvement with the GIA network in Europe. The FIT claimed responsibility for an attack in February against a Tunisian border post on the Tunisia-Algeria border in which seven border guards were killed, but some officials blame the GIA possibly in conjunction with the FIT for the attack. As of 31 December, there were no similar incidents.
