Tonight on Special Report with Brit Hume:

A few U.S. military units cross into the "red zone" around Baghdad as others cautiously make their way into Saddam Hussein's seat of power, taking on stubborn clusters of resistance.

Plus:

• Trading fire with Iraqis hidden behind brick walls and hedges, U.S. Army forces spearhead the drive on Baghdad battling their way into this town 50 miles from the capital and capturing dozens of members of Saddam Hussein's vaunted Republican Guard.

• An armada of B-1, B-2 and B-52 bombers strike communication and command centers in Baghdad, and cruise missiles set Iraq's Information Ministry ablaze in the second such attack on the building in two days.

• U.S. aircraft pound Iraqi positions near the northern town of Kalak, aiding Kurdish fighters as they seize territory from Saddam Hussein's fleeing troops.

• Secretary of State Colin Powell, ranging beyond the ongoing war with Iraq, demands that Iran halt its quest for weapons of mass destruction and that Syria cease supporting terrorism.
