A rare daytime US airstrike in Sadr City on Thursday came as residents said that soldiers were warning them to leave parts of the district, which is a bastion of support for the anti-American cleric Moqtada al-Sadr.
Residents of this city's embattled Sadr City district are growing increasingly anxious that an escalation in fighting is imminent. They reported that soldiers with loudspeakers warned people in one section to move out, while others said that on Thursday, for the first time, the US carried out daytime airstrikes.
The vast sector of 2.5 million mostly poor Shiites has been the scene of sporadic and sometimes intense fighting for seven weeks as Iraqi and US forces have pushed in to rid the area of militiamen loyal to the Shiite cleric Moqtada al-Sadr. But Thursday's fighting, which officials in Sadr City hospitals said left at least 11 Iraqis dead, surprised some residents with its timing.
"We've had this kind of attack at night, but this was the biggest attack we've had in the daytime," said Abu Hawaraa, a media adviser to the Sadr movement's office in Sadr City. He said US forces also entered a normally quiet northern section of the district.
That incursion followed two militant rocket attacks in three days on central Baghdad parks. Thursday's rocket fire killed two people in a park along central Sadoon Street.
The US has increasingly relied on airpower – unmanned drones, helicopter gunships, and bombers – to carry out the antimilitia campaign in Sadr City, saying such methods more accurately reach targets in such crowded urban settings. US and Iraqi military officials accuse the militants of using residents as human shields as they carry out mortar and rocket attacks on the fortified Green Zone of Iraqi and US government offices a few miles south.
