BAGHDAD, March 8 (Reuters) - The U.S. military commander in Iraq said on Thursday he currently saw no immediate need to request more U.S. troops other those already announced. General David Petraeus, in his first news conference in Baghdad since taking command of U.S. forces in Iraq last month, said he had discussed with his second in command on Thursday whether he had enough troops for his current mission in Iraq. "Right now we do not see other requests (for troops) looming out there. That's not to say that some emerging mission or emerging task will not require that, and if it does then we will ask for that," Petraeus said.
