Four people were killed and 15 wounded in a car bomb attack at a mosque north of the Iraqi capital Baghdad during celebrations marking Eid, the end of Ramadan, the US military said Thursday.
The bomb exploded on Wednesday at the parking lot of the Sayid Mohammed mosque in Balad, 75 kilometres (46 miles) north of Baghdad in the Sunni Salaheddin province, as devotees gathered to mark the end of the Muslim fasting month, the military said.
"There was no damage to the mosque," the military said in a statement.
It said mild weather and a festive atmosphere had drawn crowds to the mosque in the early afternoon.
A suicide car bomb attack killed 23 at a village near Balad in February.
Iraq has seen a downward trend in violence since the middle of last year, although bloodshed spiked in March and April during clashes between Shiite militiamen and US-led security forces.
