Tonight on Special Report with Brit Hume:

The British government, facing an internal revolt and blind-sided by American comments that its military assistance might not be necessary, on proposes new conditions for Iraqi disarmament that it hopes will be acceptable to the U.N. Security Council.

Plus:

• The Air Force drops its largest non-nuclear bomb on a test range in Florida, sending Saddam Hussein a powerful message about the weaponry Iraq would face in a possible war.

• Serbian Prime Minister Zoran Djindjic -- who spearheaded the revolt that toppled former President Slobodan Milosevic in October 2000 -- is assassinated by gunmen who ambushed him outside the government complex.

• The United States and its allies intensify searches along the border between Afghanistan and Pakistan for terrorists they fear may respond to war against Iraq with attacks.

• Plaintiffs in the legal challenge to last year's campaign finance reform law say that it may be too late for the U.S. Supreme Court to tackle the case this term, but a lower court's ruling — expected any day — could stay a soft money ban for now.
