A series of explosions left at least 15 people dead and dozens wounded in Iraq Sunday. A car bomb detonated outside the Palestine Hotel in downtown Baghdad, killing at least six people and injuring 16, police said. Another car bomb exploded in the parking lot of a government-run newspaper in the capital Sunday, killing at least three people and injuring 30. A bomb exploded in the town of al-Khalis, on the outskirts of Baqouba just north of Baghdad, killing six and wounding more than a dozen, police said. The attacks occurred a day after Prime Minister Nouri al-Maliki appealed to Iraqis to support his national reconciliation plan to end sectarian fighting between Shiites and Sunnis, and terrorism by Sunni Arab insurgents.
