The defence secretary also issued a new warning to Iran not to interfere in the reconstruction of Iraq. Mr Rumsfeld said Iran was “being unhelpful today with respect to Iraq”. “Iran should be on notice; efforts to try to remake Iraq in Iran’s image will be aggressively put down,” he said. Mr Rumsfeld’s comments about Iraq came amid further accusations from Washington that Tehran has been harbouring fugitive members of Osama Bin Laden’s al-Qaeda network and trying to develop nuclear weapons.
