TUNIS: Aid workers accused of assisting irregular migration to Tunisia went on trial on Monday, as Amnesty International criticized what it called “the relentless criminalization of civil society” in the country.

Six staff members of the Tunisian branch of the France Terre d’Asile aid group, along with 17 municipal workers from the eastern city of Sousse, face charges of sheltering migrants and facilitating their “illegal entry and residence.”

If convicted, they face up to 10 years in prison.

Migration is a sensitive issue in Tunisia, a key transit point for tens of thousands of people seeking to reach Europe each year.

A former head of Terre d’Asile Tunisie, Sherifa Riahi, is among the accused and has been detained for more than 19 months, according to her lawyer Abdellah Ben Meftah.
