American forces discovered a car bomb Tuesday in a parking lot near the offices of the U.S.-appointed Iraqi Governing Council (search), the U.S. command said.

The car rigged with explosives was found at Gate 2, a high-security checkpoint manned by U.S. troops, the command said. U.S. troops sealed off the area as bomb disposal experts tried to defuse it.

The gate is close to the offices of the Governing Council and a short distance from a convention center where the U.S.-led coalition holds briefings for national and international media.
