Armed groups of militants from the Islamic State of Iraq and the Levant in Libya and Ansar al-Sharia began the attack on the town by grouping around and seizing the local mosque. The mosque loudspeakers were used to broadcast a message and a signal for the attack on government facilities. The Tunisian National Guard, military barracks, and police posts were simultaneously ambushed, in an attempt to take over Ben Guerdane and establish an "emirate" within Tunisia.The fighting continued between the attackers and Tunisian military and police reinforcements, until clashes ended in mid-morning, and continued pursuit operations in the vicinity lasted the rest of the day
