“Hundreds of Iraqis converged on volunteer centers across Baghdad on Saturday in response to a call by Iraq’s highest Shiite cleric to fight back against a Sunni jihadist group making rapid gains across the north. Iraqi Shiite volunteers were responding to Ayatollah Ali al-Sistani, who on Friday issued a rare call to arms to the nation’s Shiites, setting the stage for sectarian war, local media reported.”
