A new wave of insurgent attacks in Iraq, mostly car bombs targeting Shiite-majority cities in the center and south of the country, killed at least 48 people on Sunday, officials said.
The attacks continue a surge in bloodshed that has engulfed the country for months. No one has claimed responsibility for the blasts, which targeted commercial areas and parking lots in seven cities. But systematically organized waves of bombings are used out by al-Qaida's local branch, known as the Islamic State of Iraq, to undermine confidence in the Shiite-led government.
Sometimes insurgents launch multiple attacks for two or more days in a row. On Monday, 27 people were killed in suicide attacks, bombings and shootings.
