Blasts at a major shrine set off widespread Shiite protests.
An attack Wednesday that destroyed the soaring gold dome of one of ShiiteIslam's holiest shrines is being interpreted by most Shiites here as a direct attack on their faith - and has sharply raised sectarian tensions.
It's unclear if any people were killed in the massive explosion in Samarra, about 60 miles north of Baghdad. But the destruction of the shrine may be the most emotionally charged of attacks on Shiite targets thus far in the war, and could set back already hamstrung efforts to form a government of Shiite and Sunni unity.
As citizens deserted the streets of Baghdad in the wake of the attack, many said they feared this could be a seminal moment in Iraq's low-intensity civil war.
"The war could really be on now,'' says Abu Hassan, a Shiite street peddler who declined to give his full name. "This is something greater and more symbolic than attacks on people. This is a strike at who we are."
The attack occurred shortly before 7 a.m. in the largely Sunni city of Samarra, which has remained an insurgent hotbed despite years of US operations there. It was carried out by a small group of men who somehow gained access to the usually heavily protected Askariya shrine, set demolition explosives, and then fled.
Though the shrine dates back 1,000 years, it has been rebuilt numerous times. Its current dome was built in 1905. There are no records of previous attacks on the building or its predecessors.
"This could be a tipping point,'' says Juan Cole, a historian of Shiite Islam at the University of Michigan. "At some point, the Shiite street is going to be so fed up that they're not going to listen any more to calls for restraint."
