BAGHDAD (Reuters) - Washington has made preparations to withdraw diplomats from Iraq after warning Baghdad it could shut its embassy, two Iraqi officials and two Western diplomats said, a step Iraqis fear could turn their country into a battle zone.

Any move by the United States to reduce its diplomatic presence in a country where it has up to 5,000 troops would be widely seen in the region as an escalation of its confrontation with Iran, which Washington blames for missile and bomb attacks.
