BAGHDAD (AP) _ Suicide bombers struck two Shiite mosques in Baghdad on Thursday, killing at least 24 people and wounding dozens during celebrations marking the end of the Islamic holy month of Ramadan.To the north, suspected Shiite militiamen gunned down six members of a Sunni family, including women and children, police reported.Those attacks occurred four days after a series of explosions killed 32 people and wounded nearly 100 in Shiite areas of Baghdad, raising fears that al-Qaida in Iraq is trying to provoke Sunni-Shiite reprisal killings now that the last of the American “surge” troops have left the country.In the deadliest attack, a suicide car bomber detonated his explosives about 20 yards from a mosque in Zafaraniyah in southeastern Baghdad. The blast killed 14 people, including three Iraqi soldiers, and wounded 28, police said.The death toll would likelier have been higher, but Iraqi soldiers prevented the attacker from driving closer to the mosque, police said.
