BAGHDAD — A series of car bombs exploded across Iraq’s capital Saturday night, killing at least 52 people in a day of violence that saw militants storm a university in the country’s restive Anbar province and take dozens hostage, authorities said.
The attacks in Baghdad largely focused on Shiite neighborhoods, underscoring the sectarian violence now striking at Iraq years after a similar wave nearly tore the country apart after the U.S.-led invasion that toppled Saddam Hussein. Now, with U.S. troops gone, Iraq finds itself fighting on fronts across the country, as separate clashes 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 Baiyaa district, killing nine people and wounding 22, police said. Later on, seven car bombs in different parts of Baghdad killed at least 41 people and wounded 62, police said. A roadside bomb in western Baghdad killed two people and wounded six, police said. All the attacks happened in a one-hour period and largely targeted commercial streets in Shiite neighborhoods, 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.
The gunmen detained dozens of students inside a university dorm during their attack, the officials said. Sabah Karhout, the head of Anbar’s provincial council, told journalists that hundreds of students were inside the university compound when the attack started at the school. Anbar University says it has more than 10,000 students, making it one of the country’s largest.
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 running 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-Qaeda splinter group known as the Islamic State of Iraq and the Levant.
