Tunisia's Interior Ministry has released a video that shows members of an anti-terrorism unit storming a museum and rescuing hostages.
A group of armed men attacked the National Bardo Museum in Tunis on March 18th, killing 21 people, including tourists from Japan and other countries.
The video begins with the special police forces preparing for their mission in a vehicle heading toward the museum.
They are holding automatic rifles and shields as they enter the building.
They use gestures to urge the hostages to keep silent during the rescue operation.
The video also shows guns and a grenade belonging to the assailants who were shot and killed.
The Tunisian government suspects that an Al-Qaeda-affiliated extremist group, Ansar al-Sharia in Tunisia, was behind the attack.
The authorities have arrested 23 people and are looking for Algerian and other foreign suspects.
