The Tunisian authorities said Monday that they had seized three big arms caches over the last weekend on the Tunisian border city with Libya, Ben Guerdane.
The Tunisian Interior Ministry said the arms caches contained large quantities of Kalashnikov rifles, rockets and landmines.
Tunisia has been so fearful that IS militants, who are originally from Tunisia and are now clashing in Sirte with the Misrata-led forces, would make a clandestine return to their country and thus make it vulnerable to terror and turmoil.
Back in July 2015, Tunisia announced that it had started building a separation barrier and a trench alongside the Ras Ajdair border with Libya to prohibit the infiltration of extremists into Tunisia.
However, after building the barrier, Tunisia was struck by a wave of IS terror in March 2016, when IS militants clashed with the Tunisian army, killing at least 53 people.
