According to this article at This Is London, the first bullets in this war are already flying in Iraq:
British and American troops were involved in fierce fighting near Iraq’s main port today as the war to topple Saddam Hussein began.
The firefight broke out near Basra as men of the Special Boat Service targeted the strategically vital city and the oilfields in southern Iraq.
At the same time allied troops were flooding into the demilitarised zone on the Iraqi border with Kuwait 40 miles away to take up positions for an all-out invasion.
Cruise missiles were also loaded onto B52 bombers at RAF Fairford in Gloucestershire, a clear sign that the bombardment of Baghdad could be only hours away.
The fighting reported at Basra was believed to involve British special forces and US marines in an operation to prepare landing sites for amphibious craft during an invasion.
Officially, the war still hasn’t started. Or if it has the big news media outlets aren’t saying much about it. The story above was found via the Drudge Report.
