Tonight on Special Report with Brit Hume:

Sandstorms slow coalition forces to a crawl and thwart air missions as U.S.-led forces edge within 50 miles of Baghdad, Saddam Hussein's hub of power.

Plus:

• About 500 Iraqis have been killed in the last two days by 3rd Infantry Division's tanks and mechanized units as they swept through southern Iraq.

• British Prime Minister Tony Blair, preparing for a hasty summit in Washington to discuss postwar Iraq, says there are bound to be "difficult days ahead" for coalition forces.

• Huge explosions shake buildings in Baghdad, apparently from U.S. forces bombing Iraqi positions on the city outskirts. With coalition troops closing in, the streets are nearly empty as people hunker down in anticipation of the battle for Baghdad.

• Pentagon officials complain bitterly about what they call "deadly deceptions" by Iraqi troops pretending to surrender to U.S. forces and then firing on the Americans.
