An Iraqi man holds up a portrait of Shiite cleric Grand Ayatollah Ali al-Sistani during a demonstration in the central Shiite Muslim shrine city of Najaf on June 14, 2014 to show support for his call to arms. Sistani's yesterday call to defend the country against the offensive spearheaded by the jihadist Islamic State of Iraq and the Levant (ISIL) came as US President Barack Obama said he was exploring all options to save Iraq's security forces from collapse.
