Fears of a civil war in Iraq grew Sunday after bombings in the country’s two holiest Shiite cities left 66 dead and injured over 200 more. The deadliest bombing came in the center of Najaf just 300 yards from the holy Imam Ali Shrine. 52 died in the attack. In the neighboring city of Karbala another 14 died in the city’s deadliest attack in nine months. Sunni fighters have been accused of carrying both bombings. One prominent Shiite cleric said, “They are trying to ignite a sectarian civil war and prevent elections from going ahead on time.”
