Tens of thousands of Tunisians attended a march in their country's capital, Tunis, on Sunday to denounce extremist violence following the attack on the National Bardo Museum.

Waving Tunisian flags and carrying banners reading "Together against terrorism", the demonstrators marched through central Tunis, by the site of the deadly March 18 shooting that claimed twenty-two lives of mainly foreign tourists, as well as two gunmen.

French President Francois Hollande, Italian Prime Minister Matteo Renzi and several foreign ministers and legislators from other countries are joining an anti-terrorism ceremony in Tunis after the march.

The Tunisian government called on all major political parties to join the march from the seat of government at Bab Es-Saadoun to the museum.

Speaking on Sunday morning before heading to Tunisia, Hollande said it was important to show solidarity with Tunisia, which became the latest victim of extremist violence and was the country that led the Arab Spring revolt across the region.

As a result of the 2011 revolution, Tunisia built a democratic system, which was deeply shaken by the museum attack, for which the Islamic State group claimed responsibility.

16. SOUNDBITE (French) Francois Hollande, French President:

"Of course it's (Tunis march) important. It's important because it's a demonstration of solidarity and we had four French people killed there (in Tunisia), victims of terrorism. So it was necessary to participate in the march. The Tunisians wanted France to be present and France wanted to stand side-by-side with the Tunisians, who let's not forget, began the Arab Spring and were victims with many other citizens from different countries of a heinous terrorist act. There will be several heads of state and government present in Tunis. I will be going in a few hours and we will march. Let us not forget what happened on 11 January (Charlie Hebdo attacks), a demonstration of solidarity for France and the values it represents, well today it is for Tunisia and also the values they represent in the Arab world and beyond."
