"BAGHDAD -- In the latest proposal to curb the seemingly unstoppable violence in Baghdad, the Iraqi government is planning to build a defensive barrier around the city to keep out terrorists and militants who might be planning attacks.
Iraq's Interior Ministry said Friday that the government wants to dig a trench encircling the capital. At a news conference in Washington, President Bush said at least part of the barrier would be a berm."
