Tunisia broke up four Islamist militant cells and seized explosives, poisonous gas and drone aircraft.
The militants were planning a “series of attacks against vital targets in the country, through stabbing, poisoning, cars attacks and detonation,” the interior ministry said, without identifying any targets.
The seizures came a month after a woman blew herself up in the Tunisian capital and wounded 15 people in an attack ending a period of calm after dozens died in militant attacks three years ago.
Tunisia was the only country to oust a long-serving autocrat during the “Arab Spring” uprisings without triggering large scale unrest or civil war – and won widespread praise for its democratic transition, new constitution and free elections.
Authorities estimate 3,000 Tunisians joined Islamic State and other jihadist groups in Iraq, Syria and neighbouring Libya, while high unemployment has stoked unrest in southern and central areas.
