Suicide attack kills 22 in Abu Ghraib

BAGHDAD, Iraq (CNN) - At least 22 people were killed and 40 were wounded in a suicide bombing Wednesday evening in Abu Ghraib, an Interior Ministry official said.

The bomber detonated his explosives at a mourning gathering in the predominantly Sunni location about 20 miles west of Baghdad.

Police in the nearby city of Falluja said the mourning gathering was for the principal of a technical school in the village of Abu Minasir in Abu Ghraib, who was shot dead Monday. The principal's cousin is a senior police officer in Falluja and his brother is a leading member of the Sons of Iraq or Awakening, a movement of anti-al Qaeda Sunni groups in the area.

Police and Awakening members have been a target for al Qaeda in Iraq.
