BAGHDAD -- The mayor of an Iraqi town north of Baghdad says at least 21 people were killed and dozens injured when a suicide bomber detonated an explosives vest in a crowded cafe.

The mayor, Mohammed Maaruf, says that most of the dead and wounded were men playing dominos and drinking tea in the cafe when the explosion happened Friday evening.

The blast took place in the town of Balad Ruz, 45 miles (70 kilometers) northeast of Baghdad.

The neighborhood where the explosion occurred is home to many Shiites of Kurdish ethnicity and many of the dead and wounded were Shiites.

The bombing broke what has been a period of relative calm across Iraq.
