Italian, German, Polish and Spanish tourists were among those killed in the museum attack, the Prime Minister told the reporters on Wednesday. Two gunmen, a Tunisian civilian and a policeman were also killed when security forces stormed the building in an effort to end the hostage crisis.
Tunisian Prime Minister Habib Essid has named two gunmen behind the attack as Yassine Abidi and Hatem Khachnaoui.
The assailants are "probably" Tunisian, according to the interior ministry spokesman. The authorities gave no further details about the attackers but said there could be two or three accomplices still at large.
The gunmen stormed the Bardo National Museum, located adjacent to the parliament building, where they took several tourists hostage, and killed some of them.
