BAGHDAD: A suicide bomber has targeted a Shia mosque in central Baghdad, killing at least 17 worshippers, Iraqi officials said.

A police officer said the attacker blew up his explosives-laden vest as people were leaving the al-Khairat mosque in Baghdad's Sinak commercial area following noon prayers on Monday.

He said at least 25 people were wounded in the explosion.

The attack comes a day after a suicide bombing targeted a Shia mosque in the capital's western Harithiya neighbourhood, killing 28 worshippers.

A medical official confirmed the casualty figures. Both officials spoke on condition of anonymity as they were not authorised to talk to media.
