In al-Washash, some small concrete blocks have been placed across a road and the protesters say the U.S. is planning to replace them with a high wall next week.

"The occupiers are planning to build a wall around our area but we see that as them putting the area under siege," said another tribal leader who did not give his name. "This is a secure area and this is a peaceful demonstration to condemn it."

While the march passed peacefully, police said two civilians were wounded in clashes with the Iraqi army afterwards.

U.S. air strikes on the neighborhood in September killed at least 14 people including one woman and destroyed 11 houses, Iraqi police and residents said. The U.S. military said its troops came under fire from gunmen on rooftops in the area.
