TUNIS (Reuters) -Residents entered the state-run Tunisian Chemical Group's (CGT) phosphate complex in the southern city of Gabes on Saturday, demanding its closure to prevent environmental pollution and respiratory illnesses, witnesses said. The protest highlights the pressure on President Kais Saied's government, already strained by a deep economic and financial crisis, to balance public health demands with the production of phosphate, Tunisia's most valuable natural resource. "Gabes has turned into a city of death, people are struggling to breathe, many residents suffer from cancer or bone fragility due to the severe pollution," Khaireddine Dbaya, one of the protesters, told Reuters.
