Hundreds of Tunisians marched through the capital Tunis on Saturday to protest a severe environmental crisis caused by pollution from a state chemical plant in Gabes, as protests that began there widen outside the southern city.

The protest is the latest in a series of demonstrations that have underscored growing public frustration over the government’s handling of pollution and worsening state of public services, marking the biggest challenge to President Kais Saied since he seized all power in 2021.
