Baghdad (AP) At least 50 people are dead in a suicide attack today at a funeral in Iraq.

It happened in a town north of Baghdad at a funeral for two Sunni brothers, who were killed in an attack yesterday. They were members of a so-called awakening council. Those are the U.S.-funded citizens groups who defend towns and villages, joining American troops in fighting Iraq's branch of Al-Qaida militants.

Police say the suicide attacker walked into a tent crowded with mourners and blew himself up.

The awakening councils have been given some of the credit for a return to relative calm in Sunni areas. Today's attack is the latest in a string of attacks raising fears that Sunni militants are reorganizing.

Bombings Tuesday killed 60 people in four major cities in central and northern Iraq.
