BAGHDAD — A suicide bomber killed at least nine people Thursday outside a Shiite mosque in the Iraqi city of Baqubah during the run-up to the Islamic sect's major religious holiday, police said.
The attacker detonated his explosives as worshipers were making evening preparations for the festival of Ashura, which falls on Saturday. Police said 14 people were wounded in the blast.
The attack in the capital of Diyala province came a day after a female suicide bomber struck in the nearby town of Khan Bani Saad, killing eight people.
A witness to Thursday's blast said he watched a stranger arguing with a police officer who had been searching people entering the area by the mosque.
"I saw the bomber explode like a balloon with my own eyes," said Nussaif Jasim, a cafe owner. "It was so fast, something unbelievable. Many people were outside the mosque. Many were harmed, even children.
"The policeman was torn to pieces," Jasim said.
Sunni extremists targeted Ashura celebrations in 2004, with suicide bombings killing about 180 people in attacks in Karbala and at the Shiite shrine of Kadhimiya in Baghdad.
For this year's Ashura, the government has put a vehicle ban in effect, with some exemptions, in Baghdad and much of central Iraq in hope of staving off large-scale attacks against Shiite pilgrims.
On Ashura, the 10th day of the Muslim month of Muharram, Shiites mourn the death of Imam Hussein, a grandson of the prophet Muhammad. Hussein and his followers were slaughtered in 680 on the plains of Karbala by the forces of Islamic ruler Yazid. Hussein's martyrdom and the death of his father, Ali, before him were the root of the schism between Sunni and Shiite Islam.
The celebrations for Ashura, in which hundreds of thousands flock to Karbala to mourn Hussein's death and reenact his last battle, have become symbolic of the ascendancy of Iraq's Shiite majority. Shiites were restricted in celebrations of their faith under Saddam Hussein's Sunni-dominated regime.
Diyala province, with its mixed Sunni-Shiite population, has been a magnet for sectarian violence. Many Sunni militants who fled Baghdad in the face of a U.S. military crackdown last year are believed to have taken refuge in Diyala, to the north and east.
Red, black and green flags were aloft across Shiite areas of Iraq as the faithful prepared for Ashura. At the Kadhimiya shrine, the scene of the violence in western Baghdad on Ashura four years ago, Iraqi army troops and police officers had sealed off streets to protect the thousands of pilgrims who will celebrate this year's festival there.
