Iraqi police say a suicide bomber killed 22 people and wounded at least 35 at the funeral of a Sunni school principal west of Baghdad.

The bomber blew himself up in a funeral tent in the village of Abu Minasir. The funeral was for a grammar school principal who was shot and killed Tuesday.

Many Sunnis opposed to al-Qaida were at the funeral Wednesday. Col. Faisal al-Zubaie said 22 people died in the attack.
