WASHINGTON (Reuters) - U.S. troops will probably need to play a bigger role "advising and assisting" Iraqi forces on the ground in the future, the highest ranking U.S. military officer said in an interview broadcast on Sunday.
U.S. forces have been bombing Islamic State fighters in Iraq since August and expanded the air campaign to Syria last month. The White House has repeatedly said it will not send ground troops back to Iraq, where President Barack Obama withdrew U.S. forces in 2011.
