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 neighbourhoods, underscoring the sectarian violence now striking at Iraq years after a similar wave nearly tore the country apart following the U.S.-led invasion that toppled Saddam Hussein. Now with U.S. troops gone, Iraq founds itself fighting on fronts across the country, as separate clashes in a northern city killed 21 police officers and 38 militants, officials said.
