(KUNA) -- Six Iraqi people were killed and 12 others injured in a suicide attack by a woman in Diyali Province, northeast of Baghdad, a security source told KUNA on Tuesday. A woman blew herself up near a police station at Jalola in northern Diyali, killing four Iraqis and wounding another 12 people, the Iraqi security source said. The injured Iraqis were taken to hospital for medical treatment, the source added, but failed to reveal if some of them were in critical condition. Diyali occasionally sees suicide attacks by women enlisted by the terrorist Al-Qaeda organization, according to US forces in Iraq.
