Tunisia's interior minister said security forces had almost wiped out an Islamist militant group linked to al-Qaida during a crackdown launched after two deadly attacks on tourists.
Clashes last week killed leaders, including two veteran Algerian militants, from the Okba Ibn Nafaa brigade, blamed for an assault on the Bardo Museum in Tunis in March, minister Najem Gharselli told reporters late on Sunday.
The North African country has come under growing international pressure to show it is in control of militants after a gunman also killed 38 holidaymakers at a beach hotel in Sousse last month, an attack claimed by the Islamic State group.
"After we killed some of their leaders in (the central region of) Gafsa a few days ago we have now destroyed 90 percent of Okba Ibn Nafaa," the minister said.
Okba Ibn Nafaa, allied with al-Qaida's North African wing, was among the most active of hardline groups that emerged after Tunisia's 2011 "Arab Spring" uprising ousted autocrat Zine El-Abidine Ben Ali.
Ties between the groups are often fluid and analysts say younger fighters may be increasingly drawn to Islamic State's gains in Iraq, Syria and neighboring Libya.
Authorities say more than 3,000 Tunisians have left the country to fight for Islamic State and other militant groups on other battle fields. But the minister said the organization still had no significant presence in Tunisia.
