US forces on 23 March discovered a large chemical weapons facility near the city of Najaf, according to reports from the US' Fox News and the Jerusalem Post, who have reporters embedded with the troops. The installation was handed over to the First Brigade of the US 3rd Infantry Division by the Iraqi troops tasked with guarding it. Reports indicate that the factory covers a site of about 100 acres adjacent to a military barracks and had been camouflaged to avoid detection from the air. US Lieutenant-General John Abizaid at the Central Command in Qatar told reporters that the reports could not be confirmed, and defence officials in the US also urged caution. Abizaid said that two Iraqi generals had been taken prisoner at the Najaf site and were providing information.
