Tunisian security forces have raided and killed three alleged leaders of an al-Qaeda-linked Takfiri terrorist group blamed for terrorist attacks on Tunisia’s tourist attraction sites, the country’s interior minister says.

“The operation carried out on Friday by our security forces in cooperation with the army in the region of Gafsa resulted in the elimination of five dangerous terrorists, including three senior leaders” of the Okba Ibn Nafaa Brigades, said Najem Gharsalli in a Sunday press conference as cited in an AFP report.

The alleged Takfiri leaders were identified as Tunisian nationals Mourad Gharsalli and Hakim Hazi, as well as Algerian native Lounis Abou Fath. The other two suspects killed in the raid, however, have not yet been identified.

The minister further said that Abou Fath had been on the wanted list of Algerian authorities since 1994.

Meanwhile, officials in Tunis have also blamed the Okba Ibn Nafaa Brigades, which has been referred to as the country’s main Takfiri terrorist group, for other attacks, including the mass killing of 21 foreign tourists and a police officer back in March at the Bardo National Museum in the capital of Tunis.

The killing of the alleged al-Qaeda leaders come nearly three weeks after 38 individuals, mostly British citizens, were shot dead by a lone gunman, identified as 23-year-old student Seifeddine Rezgui, on the beaches of a resort town near Sousse on the northern Mediterranean coast. The attack was claimed by the Takfiri ISIL terror group.

Following the incident, senior Tunisian officials declared that the government had deployed 1,377 armed security agents on the country’s hotels and on beaches, saying that British authorities are also “assisting” with the criminal investigation into the carnage.

“As part of the security cooperation between Tunisia and Britain, 10 British investigators are working on the probe,” said Tunisia’s Minister of Government Relations Kamel Jendoubi.

British media also reported at the time that 16 senior Metropolitan police detectives, forensic specialists and family liaison officers had arrived in Tunisia, with more forces expected to join them in a bid to help with the probe and prevent further terrorist attacks.

Meanwhile, Tunisian authorities have announced the arrest of 127 suspected terrorists since last month’s beach massacre.
