Authorities in Iraq say bombs kill 44 in capital

BAGHDAD - A series of car bombs exploded across Iraq's capital Saturday night, killing at least 44 people in a day of violence that saw militants storm a university in the country's restive Anbar province, authorities said.

The attacks in Baghdad largely focused on Shiite neighborhoods, underscoring the sectarian violence now tearing at Iraq years after the withdrawal of U.S. troops. Meanwhile, separate fighting in a northern city killed 21 police officers and 38 militants, officials said.

The first Baghdad attack took place Saturday night in the capital's western district of Baiyaa, killing nine people and wounding 22. Later on, seven car bombs in different parts of Baghdad killed at least 35 people and wounded 62, police said. All the attacks happened in a one-hour period, authorities said.

Hospital officials confirmed the casualty figures. All officials spoke on condition of anonymity because they were not authorized to release details to journalists.

Violence in Iraq has spiked following a security crackdown on a Sunni protest camp last year. According to United Nations figures, 8,868 people were killed in Iraq in 2013.

Earlier Saturday, gunmen killed three police officers on guard at the gate of Anbar University, a police and a military official said. The gunmen then detained dozens of students inside a university dorm, the officials said. Sabah Karhout, the head of Anbar's provincial council, told reporters that hundreds of students were inside the university compound when the attack started.

Ahmed al-Mehamdi, a student who was taken hostage, said he awoke to the crackle of gunfire, looked out the window and saw armed men dressed in black racing across the campus. Minutes later, the gunmen entered the dormitory and ordered everybody to stay in their rooms while taking others away, he said.

The Shiite students at the school were terrified, al-Mehamdi said, as the gunmen identified themselves as belonging to an al-Qaida splinter group known as the Islamic State of Iraq and the Levant. The Sunni terror group, fighting in Syria with other rebels trying to topple President Bashar Assad, is known for massive, bloody attacks in Iraq as well often targeting Shiites that they view as heretics.

The Islamic State did not immediately claim the attack on the school, which says it has more than 10,000 students, making it one of the country's largest.

Several hours later, gunmen left the university under unclear circumstances. Students then boarded buses provided by the local government to flee the school, though gunfire erupted as security forces attacked retreating militants, police said.

"We thank God that this crisis ended almost peacefully and no student was hurt as far as I know," al-Mehamdi said by mobile phone from inside a bus that took him to safety.

Security officials said authorities wanted to wait for bomb disposal experts before entering any building on campus out of fears that the fleeing gunmen planted explosives. Government forces also came under sniper fire, officials said.

"Not a single student or a university staff member was hurt during the raid. All of them went home and their ordeal is over," Karhout said.

In the northern city of Mosul, clashes continued Saturday for a second day between security forces and Sunni militants trying to seize neighborhoods there. Police and morgue officials said that fighting since dawn Saturday killed 21 police officers and 38 militants.

The latest violence has been fueled by Sunni Muslim anger at the Shiite-led government in Baghdad, as well as the civil war in neighboring Syria. The Islamic State has carried out scores of deadly attacks on both sides of the border and imposed a brutal form of Islamic rule in territories under its control.

Those attacks include a coordinated assault April 21 on a private Shiite college in Baghdad that killed four police officers and one teacher.

Al-Qaida-linked fighters and their allies seized Fallujah and parts of Ramadi in late December after authorities dismantled a protest camp of Sunnis angry at what they consider their second-class treatment by the Shiite-led government. Fearful of setting off violence, security forces withdrew from the area, allowing militants to seize the cities. In April 2013, a similar dismantling of a Sunni protest camp in Hawija sparked violent clashes and set off the current upsurge in killing.

The government and its tribal allies are besieging the rebel-held areas, with fighting reported daily. Tens of thousands have fled the violence.
