Meanwhile, Defense Secretary Donald Rumsfeld is in Iraq on an unannounced visit. Speaking to reporters en route from another surprise stop in Afghanistan, Rumsfeld said the Iraqi government is not ready to decide on a timetable for the withdrawal of US troops. He also rejected Iraqi calls for revoking the immunity granted to US forces in Iraq. His comments came one day after Iraq’s human rights minister said he will bring the request to revoke US immunity to the United Nations.
