U.S. and Iraqi forces have set up barriers elsewhere in Baghdad to prevent attacks, but the current project is apparently the first to divide neighborhoods by sect.
In other news, Amnesty International says Iraq is now among the countries with the highest use of the death penalty in the world.
In a report today, the rights group said Iraq executed at least 65 people in 2006, including two women. It said only China, Iran, and Pakistan used the death penalty more frequently.
The death penalty was suspended after the U.S.-led coalition toppled Saddam Hussein in 2003, but Iraqi authorities reinstated it one year later. The former Iraqi leader was himself executed in December.
