(BAGHDAD) -- The mayor of what had been one of Iraq's most restive cities during the war was assassinated Wednesday.
The death of Fallujah Mayor Adnan al-Jalbawi adds to the growing fear that the country is again spinning out of control during Iraq's most violent year since 2008.
Witnesses said Jalbawi was visiting a sewage pumping station in the city when he was gunned down by unknown assailants. No one claimed responsibility for the attack.
Lately, Sunni insurgents with ties to al Qaeda have been blamed by the Shiite-led government for the rise in violence, which has claimed nearly 6,000 lives in 2013.
During the height of the Iraq war, Fallujah was one of the strongholds of the Sunni insurgency. It was there in March 2004 that four U.S. private contractors were brutally murdered by an angry mob.
