BAGHDAD, April 20, SPA -- U.S. soldiers are building a three-mile (five kilometer) wall to protect a Sunni Arab enclave that is surrounded by Shiite neighborhoods in an area of the capital that «has been trapped in a spiral of sectarian violence and retaliation,» the military said.

It said the concrete wall, including barriers as tall as12 feet (3.5 meters), «is one of the centerpieces of a newstrategy by coalition and Iraqi forces to break the cycleof sectarian violence» in Baghdad.--SPA www.spa.gov.sa/442616
