Relatives carry the coffin of Rasha Hassan, 22, before her burial in the Shiite holy city of Najaf, 160 kilometers (100 miles) south of Baghdad, Iraq, Thursday, Jan. 5, 2012. A wave of explosions struck two Shiite neighborhoods on Thursday, killing and injuring dozens of Iraqis, police said, and intensifying fears that insurgents are stepping up attacks after the U.S. troop withdrawal that was completed last month.
