A Shiite member of the Iraqi pro-government forces flashes the V-sign for "victory" as he stands in front of a mural depicting the Islamic State (IS) group's flag on the outskirts of the Iraqi town of Ad-Dawr, on March 6, 2015, during a military operation to retake the Tikrit area from jihadists. Some 30,000 Iraqi security forces members and allied fighters launched the operation to retake Tikrit on March 2, 2015, the largest of its kind since IS overran swathes of territory last June.
