The move, which lessens the pressure on politicians in Baghdad, came as rare bombings in the south killed 33 people and wounded dozens. / AFP / HAIDAR MOHAMMED ALI        (Photo credit should read HAIDAR MOHAMMED ALI/AFP/Getty Images)

Mourners gathered for a funeral near Baghdad grappled with even more loss Sunday when a suicide bomber attacked the funeral tent, killing six people, police said.

Another 11 people were wounded in the blast in Abu Ghraib, west of Baghdad, police said.

The funeral was for a member of the Sahwa – Sunni tribal forces that have fought against al Qaeda. Some members of the Sahwa, also known as the Awakening Council, are now fighting ISIS.

ISIS claimed responsibility for the attack, according to a statement circulated on social media by supporters of the terror group.

Abu Ghraib was also the site of an infamous prison abuse scandal in which 11 U.S. soldiers were convicted of crimes such as conspiracy, dereliction of duty and maltreatment of detainees.
