On 2 August 2014, after Lebanese security forces arrested an al-Nusra Front commander, fighters from al-Nusra Front and ISIL surrounded Lebanese Army checkpoints in Arsal before attacking them and storming the northeastern town's police station, where they took at least 16 policemen hostage.[11][12] The militants then proceeded to take control of the town,[13] and captured two soldiers who were freed by the military later in the day.[11] The fighting continued into the next day and left 30 militants,[14] 10 soldiers and two civilians dead. 25 soldiers were wounded and 13 were missing and presumed captured.[15] Two of the missing soldiers were rescued the same day.[16]
On 4 August, the death toll had risen to 17 soldiers,[17] 50 civilians and 50 militants. 86 soldiers had been wounded and the number of missing had reached 22,[6] while 135 civilians and 15 militants were wounded.[18] Two of the dead civilians were infant Syrian refugees.[19] The military had advanced and captured[6] the technical institute building, which was seized by the militants the previous day,[16] as the town came under heavy shell fire from multiple directions.

On 5 August, the military was attempting to capture two government buildings, while three soldiers and three policemen were released by the militants.[21] During the day's fighting, the ISIL commander for the Arsal area was reportedly killed,[1] while al-Nusra forces retreated from the town.[22] In the evening, a 24-hour cease-fire started.[13]
On 6 August, another three soldiers were released, while 10 soldiers and 17 policemen remained as captives.[23]
By 7 August, a fragile truce was established as ISIL forces also retreated from the town and redeployed along the border with Syria.[2][24][10] Their hideouts there were subsequently bombed by the Syrian Air Force, resulting in dozens of wounded militants. On 22 July 2017 Hezbollah controlled 90% of Jroud arssal.[25]
Two days later, the Lebanese Army entered Arsal in full force and re-established control over checkpoints that the militants had previously seized, while another soldier died of his wounds, bringing the military death toll to 18,[26] which was updated to 19 by 12 August. 60 militants were also confirmed dead,[4] as well as 42 civilians. The total number of civilians wounded was estimated at 400.[10]
