(CNN) -- At least 14 people died and more than three dozen others were injured on Sunday in a wave of bombings across Baghdad, police said
The strikes, car bombs and roadside bombs, targeted mostly Shiite areas across the capital. Sectarian violence between Sunnis and Shiites has raged in recent months.
The latest attacks occurred after several deadly assaults last week during Ashura, a major holy day on the Shiite Muslim calendar that commemorates the death of Imam Hussein, grandson of the Prophet Mohammed.
Ashura is over, but Shiites now observe a holy period called Arbaeen that ends in about 30 days. Shiites remember the death of Imam Hussein during that time.
Since the U.S.-led invasion in 2003, Shiites have gained new freedom after Saddam Hussein's regime was toppled. They have expressed their religious beliefs and customs openly and in great numbers.
Since then, thousands of Shiites have been killed in attacks during these commemorations. Al Qaeda in Iraq, the Sunni extremist movement, is believed to have carried out most of these assaults.
After Sunnis, Shiites represent the largest denomination in the Muslim world.
