French President Francois Hollande, Italian Prime Minister Matteo Renzi and other foreign officials joined thousands of Tunisians taken to the streets and chanting "Tunisia is free! Terrorism out!" the BBC said. The world leaders also attended a ceremony at the Bardo museum where a stone tablet was dedicated to the memory of the attack victims.
Earlier this day, Tunisian authorities claimed to have killed nine militants, including alleged leader of the Bardo attack, Lokman Abu Sakhra, during a raid in the southern Tunisian region of Gafsa late on Saturday, according to the BBC.
The Islamic State (ISIL) militant group, which is mostly active in Syria and Iraq, claimed responsibility for Bardo museum atrocities.
Up to 3,000 Tunisians are estimated to be fighting alongside Islamists in Iraq and Syria, the International Centre for the Study of Radicalisation and Political Violence says.
