A fighter from the pro-government forces loyal to Libya's Government of National Unity (GNA) looks at GNA forces' vehicles burning after a suicide bomber of the Islamic State group (IS) detonated his explosives close to a group of soldiers on August 16, 2016 in an area of central Sirte, known as District Two. Libyan pro-government forces said they seized control of District Two as they tried to flush out the last Islamic State group fighters in the coastal city of Sirte. Dozens of US air strikes this month have helped to weaken IS's hold on Sirte, which the jihadists seized last year and established as their main base outside Syria and Iraq. / AFP / STR (Photo credit should read STR/AFP/Getty Images)
