Insurgents have attacked Shi'ite Muslims in Baghdad Friday, during that community's most solemn religious period.
Iraqi police and hospital officials say at least 23 people were killed and dozens wounded in three separate attacks. In two of them, suicide bombers approached worshippers leaving Friday prayers at two mosques and detonated their explosives.
Authorities say the third attack was from a mortar shell that landed on a cafe near a mosque in a Shi'ite neighborhood.
The mosques were packed with Shi'ite worshippers marking the first two days of mourning for the revered Imam Hussein, who was the grandson of the Prophet Mohammed. Observances will culminate Saturday.
The attacks also come a day after Iraq's Electoral Commission certified election results that solidify Shi'ite dominance in the new National Assembly.
