BAGHDAD (AP) - A series of car bombs have exploded across Iraq's capital, killing at least 44 people.
The attacks took place over a one-hour period Saturday night, largely focusing on Shiite neighborhoods. The first took place in Baghdad's western district, killing nine people and wounding 22. Police say seven car bombs followed in different parts of the city.
Meanwhile, separate fighting in a northern city of Mosul killed 21 police officers and 38 Sunni militants. It was the second day of clashes there.
Violence also hit western Anbar province, where militants stormed a university, taking students hostage for several hours. Police and military officials say three police officers guarding the university gate were killed.
One student who was taken hostage says the gunmen identified themselves as members of an al-Qaida splinter group known as the Islamic State of Iraq and the Levant. The Sunni terror group did not immediately claim the attack, and the gunmen left the university under unclear circumstances.
