A fighter from the Al-Marsa Brigade, fighting IS in Sirte, exchanges fire with nearby snipers on a frontline position near the sea front. Various Libyan army units, mainly made up of brigades ('Katibas') from the city of Misrata, have been fighting for some months now on behalf of the GNA-government (Government of National Accord, led by prime minister Al-Sarraj) against IS in Sirte, in an operation that goes by the name of Al-Bunyan al-Marsous.
