14 Sunni mourners killed in another funeral bombing in Baghdad Family grieve at the funeral of a man killed by a suicide bomber in Baghdad on Sunday. A DOUBLE bomb attack on Sunni mourners in Baghdad has killed 14 people on the third day in a row in which funerals have been attacked amid a wave of bloodshed across Iraq, officials said. Police say back-to back blasts tore through a tent set up for the funeral of one of four people killed two days before when gunmen shot up a store selling liquor in the Sunni neighborhood of Azamiyah. Monday's attack came only one day after a deadly suicide bombing on another Sunni funeral in Baghdad that left 16 dead. On Saturday, a double suicide attack on a Shiite funeral killed 72 mourners. Attacks on Shiite civilian targets - including funerals - are a hallmark of al-Qaida's Iraq branch. But it was not clear if the two attacks on Sunnis were also the work of al-Qaida, which has been known to target Sunni rivals, or part of a growing number of apparent reprisal attacks by Shiites. More than 4000 people have been killed between April and August, a level of carnage not seen since the country was on the brink of civil war in 2004-08. The reemergence of tit-for-tat retaliatory killings has raised fears that Iraq may be returning to that cycle of violence. Earlier in the day, police said gunmen broke into the home of a Shiite family in a Sunni-dominated area south of Baghdad and killed three members of a family. Two police officers say the militants attacked the house in the town of Youssifiyah early on Monday morning, killing the parents and their 16-year old son. Two other children, aged 12 and 14 years, were wounded. Youssifiyah is 20 kilometres south of Baghdad. Medical officials confirmed the figures.
