Three motorbike bombings in the southern Iraq port city of Basra killed at least nine people and wounded at least 37, police and a doctor said on Thursday, raising a previous toll.
A police lieutenant colonel said that nine people were killed and 37 wounded in the Wednesday night bombings.
But a senior official in the Basra health department said that at least 12 people were killed and more than 70 wounded in the blasts.
Both spoke on condition of anonymity.
A doctor and a police officer had on Wednesday night put the toll at eight dead and at least 22 wounded in the bombings.
Basra province police chief General Faisal al-Abadi said that the explosives-laden motorbikes, which were parked in the city centre, had detonated about 8:00 pm (1700 GMT) on Wednesday.
Violence has declined nationwide since its peak in 2006 and 2007, but attacks remain common. A total of 258 people were killed in October, according to official figures.
