Rached Ghannouchi, a prominent opposition figure in Tunisia, fainted in prison due to high temperatures, according to reports. The incident was witnessed by the daughter of Ahmed Nejib Chebbi, another well-known political prisoner. Ghannouchi has been jailed as part of a crackdown on political dissent in the country. The extreme heat in the prison is believed to have contributed to his collapse. No further details about his condition have been released. The incident highlights ongoing concerns about the treatment of political detainees in Tunisia. Human rights groups have repeatedly called for improved conditions in the country's prisons, especially during the hot summer months. Ghannouchi, a former speaker of parliament, is one of several opposition leaders detained in recent months. His health has been a subject of worry for his supporters and family. The Tunisian authorities have not commented on the incident. The daughter of Chebbi, who was visiting the prison, witnessed the fainting and reported it to family members. The incident has sparked renewed calls for the release of political prisoners and for better prison conditions. Tunisia, once seen as a model for democracy in the Arab world, has seen a backsliding on political freedoms in recent years.
