Tonight on Hannity & Colmes...

Things are developing very quickly in Iraq as U.S. forces advance to an area less than 20 miles from Baghdad and coalition troops gear up for what will be an all-out assault on the Iraqi capital.

Ground forces from the Army's 3rd Infantry Division and the First Marine Expeditionary Corps have penetrated the Iraqi capital's "red zone" today, destroying one division of Saddam Hussein's much touted elite Republican Guard as they crossed the Tigris River.

The "red zone" is the area encircling the capital where U.S. officials say Iraqi resistance will be most tenacious, and where Saddam has reportedly authorized his troops to use chemical weapons.
