Iraqi government forces raise their weapons as they hold a position on the western outskirts of Tikrit, on March 27, 2015, during a military operation to retake the city from Islamic State group jihadists. Iraqi government forces revived a stalled ground operation to retake Tikrit on March 26, 2015, following US-led air strikes that paved the way but left the anti-jihadist camp deeply divided.
