Secretary of Defense Donald Rumsfeld and Gen. Richard Myers (right), chairman of the Joint Chiefs of Staff, discuss Iraq Tuesday.
In Iraq, insurgents conducted attacks across the country Tuesday, killing more than 20 people, including several Iraqi policemen and a U.S. soldier. In Washington, top Pentagon officials encouraged Iraqis to finish work on a new constitution on schedule.
Defense Secretary Donald Rumsfeld also said that insurgents are using explosives and other weapons that are "clearly, unambiguously from Iran" -- though he said it is unclear who is making or supplying the weapons.
Noting that Iraqi security forces are increasingly taking on insurgents without U.S. aid, Rumsfeld said that in the end, a new constitution would play a vital role in defusing violence in the country.
