Dramatic video footage has emerged of the moment special forces stormed the Bardo Museum in Tunisia, where gunmen were holding tourists hostage.

Earlier, at least five gunmen stormed the museum in central Tunis, next to the country's parliament buildings, at shortly after 12pm local time, where they are reported to have taken up to 30 people hostage.

Tunisian security services besieged the museum for three hours, providing cover as some tourists fled the building for safety, before storming the building and killing two gunmen.

Security forces are believed to be hunting for others involved in the attack. Tunisian Prime Minister Habib Essid said 17 of those killed were foreigners, including nationals from Germany, Italy, Spain and Poland.

A Tunisian cleaning lady and security guard were also killed. EU Foreign Minister Federica Mogherini blamed Islamic State (Isis) for the attack.

UPDATE: A video showing Tunisian MPs singing the national anthem while locked down because of the attack has emerged on social media.

The clip was uploaded on Facebook by Maria Marihøne.

Words can’t express how sad this is. This was a symbolic attack against democracy (the Parliament) and the economy (the touristic hotspot that is Bardo). But here’s a snippet from today to show you the Tunisia I know, the Tunisians, I know.After the attack on the Bardo museum, which is situated next door to the Parliament, some of the Parliamentarians at the assembly, who were under an hour long lock-down before being evacuated, began to sing the national anthem and held a speech in defiance to terrorism. The sentiment was clear: “We will continue to fight terrorism!”A parliamentary hearing about the anti-terrorism law was due to be held today, whether this was linked or not...
