A suicide bomber struck a funeral tent in Anbar province in western Iraq on Monday, killing six mourners and wounding 15 others, an Interior Ministry source said.
The bomber blew his explosive belt among mourners who were attending a funeral on Monday afternoon in the city of Haditha, some 200 km west of Baghdad, the source told Xinhua on condition of anonymity.
Children were among the killed and wounded, the source said.
A witness who was attending the funeral and had been wounded by the attack told Xinhua that the funeral was for the mother of a former Iraqi government official.
The health authorities in the city called on the residents to donate their bloods for the wounded people, the witness said.
Anbar, the country's largest province, has been relatively calm in the past more than two years after Sunni tribes and anti-U.S. insurgent groups turned up against al-Qaida in Iraq network, cooperating with the U.S. troops and Iraqi security forces.
