Large explosions rocked Baghdad on Sunday, apparently an artillery barrage in the south of the city.
The blasts began after 9 a.m. but the cause was unclear.
The size and the pattern of the explosions suggested they were caused by a US artillery barrage directed at Sunni militant neighborhoods along the city's southern rim.
Such blasts have been heard in the evenings but they are rare at that time of day.
