A suicide bomber disguised as a policeman killed at least 53 people and wounded hundreds of others in an attack on Shia Muslim pilgrims at a checkpoint in the southern Iraqi city of Basra today.
The attack at the end of Arbain, one of the main religious observances on the Shia calendar, came as a political crisis in the Shia-led government renewed fears of a return to sectarian violence in the country.
"A terrorist wearing a police uniform and carrying fake police I.D. managed to reach a police checkpoint and blew himself up among police and pilgrims," said a police official at the scene of the bombing.
The pilgrims had been on their way to a major Shia mosque to the west of Basra, police said.
Security forces sealed off the main hospital in Basra, fearing further attacks. Weeping relatives gathered at the hospital as soldiers, police and civilians rushed blood-covered victims there. Some of the wounded were stuffed into car trunks.
"Now we have 53 killed and more than 100 wounded," said Ahmed al-Sulaiti, deputy head of the Basra provincial council. "We are waiting for more details from the security forces about the reasons behind the attack and how they managed to do it."
A provincial health official who asked not to be named put the toll at 35 dead and 90 wounded.
Arbain has been a repeated target of militants since the US-led invasion that ousted Sunni dictator Saddam Hussein.
Scores of people have been killed in attacks on pilgrims in the last few weeks, including a suicide bombing which killed at least 44 people.
Many of the incidents involved methods such as suicide bombings, the signature of Iraq's al Qaeda affiliate.
Attacks on Shi'ites have killed dozens of people since Shia Prime Minister Nuri al-Maliki's government issued an arrest warrant for a Sunni vice president, triggering a political crisis that risks scuttling a power-sharing agreement.
Violence had declined since the height of sectarian slaughter in 2006-2007, when thousands were killed in intercommunal strife. But the withdrawal of the last American troops in December has fanned worries of a resurgence.
