Bush: New Iraq troops meant for supporting roles

US President George W. Bush said Sunday that 4,600 additional troops he is sending to Iraq above an increase announced in January are slated for support roles only, and urged Congress to approve funding for the war "without any strings attached." Bush said in January after an extensive review that 21,500 additional American soldiers would be sent to Iraq to help calm Baghdad and the troubled Anbar Province. "Those combat troops are going to need, you know, some support, and that's what the American people are seeing in terms of Iraq - the support troops necessary to help the reinforcements do their job," Bush said at a news conference here with Colombian President Alvaro Uribe.
