Reuters photographer Goran Tomasevic has spent much of the past two months in Libya with fighters loyal to the GNA, mostly brigades from Misrata, as they waged ground battles with ISIS in the town of Sirte. Tomasevic: “When everyone shouts ‘Allahu Akbar’ (God is Great) I know that a tank or a cannon will fire.”

A veteran chronicler of armed conflict from the Balkans to Afghanistan to the Middle East and Africa, Goran Tomasevic has covered the instability in Libya over the last five years. But for the past three weeks, the Reuters photographer has been on the ground in Sirt, the ISIS stronghold in Libya where the U.S. launched a series of airstrikes beginning on Aug. 1. The pictures he’s made there provide a raw and intense look at the bid to retake the hometown of late Libyan dictator Muammar Gaddafi from the extremists, who seized it last year and created their largest base outside Syria and Iraq.

Reuters photographer Goran Tomasevic returned to Syria earlier this month, where he has been traveling the war-torn streets of Damascus with the Free Syrian Army. His past 24 hours were especially harrowing, as he accompanied an FSA group on an attack mission
