Over a thousand Tunisians have demonstrated in the city of Jendouba to denounce the weekend killings of four people by militants.

On Monday, the protesters gathered outside the governor's office in the city chanting "Tunisia is free, terrorism out," and "Faithful to our martyrs," AFP reported.

They also expressed their support for the security forces, chanting the national anthem and shouting "We are with you!"

On Saturday, two policemen, a prison guard as well as a civilian were killed and four other people wounded in a militant attack in Jendouba province, near the border with Algeria.

No group has yet claimed responsibility for the assault; however, Salafi militants have been blamed for similar attacks in the past.

Tunisia has been battling militants from the banned Salafi movement the so-called Ansar al-Sharia.

On December 30, 2013, leader of Ansar al-Sharia Seifallah Ben Hassine was arrested in Libya after a Tunisian court ordered an international warrant for his arrest.

At least 200 people including the supporters of the group were arrested last May following clashes between security forces and Salafis in a suburb of the capital, Tunis.

The Ansar al-Sharia is one of the militant groups formed after the Tunisian revolution, which led to the ouster of the country’s dictator, Zine El Abidine Ben Ali, in 2011.

The Tunisian government declared the group a terrorist organization last year.
