Authorities in Tunisia have arrested four suspects linked to an attack that targeted tourists at a Museum in the capital Tunis.
21 people were killed including foreign tourists while 47 were seriously injured.
A government statement confirmed the arrests saying police also arrested another group of five suspected of having ties to the cell.
The Islamic State of Iraq and the Levant group has reportedly released audio recordings claiming responsibility over the attack at the National Bardo Museum.
Islamic State said it was behind the attack on the Bardo museum, using an audio message to praise two “knights of the caliphate”.
The message, posted on Twitter accounts known to be reliable sources of IS propaganda, named the attackers as Abu-Zakariya al-Tunisi and Abu-Anas al-Tunisi.
Both men were killed by security services in a raid after they attacked the museum.
A statement described the attack as a “blessed invasion of one of the dens of infidels and vice in Muslim Tunisia”.
In an interview with France’s RTL radio, Prime Minister Habib Essid said Tunisia was working with other countries to learn more about the attackers.
One of two gunmen involved in the Bardo museum attack, named by Tunisian officials as Yassine Laabidi, was reportedly known to the authorities.
