TUNIS- Tunisian Prime Minister Habib Essid said on Tuesday Islamic State militants had carried out the huge raid on Ben Guerdan on Monday that killed 55 people in an attempt to control the town and expand their territory.
Tunisia has become increasingly concerned about violence spilling across its frontier as Islamic State has expanded in Libya, taking advantage of the country's chaos to control the city of Sirte and setting up training camps there.
Dozens of militants stormed through the border town of Ben Guerdan on Monday attacking army and police posts and triggering street battles during which troops killed 36 fighters. Twelve soldiers and seven civilians also died during the attack.
Essid said officials were still investigating whether the group of 50 militants had infiltrated across the frontier from Libya, though officials found three caches of arms, explosives and rockets in Ben Guerdan after the attack.
