BAGHDAD  The United States and Iraq will begin negotiating possible exceptions to the June 30 deadline for withdrawing American combat troops from Iraqi cities, focusing on the troubled northern city of Mosul, according to military officials. Some parts of Baghdad also will still have combat troops.

Everywhere else, the withdrawal of United States combat troops from all Iraqi cities and towns is on schedule to finish by the June 30 deadline, and in many cases even earlier. But because of the level of insurgent activity in Mosul, United States and Iraqi military officials will meet Monday to decide whether to consider the city an exception to the deadline in the Status of Forces Agreement, or SOFA, between the countries.

“Mosul is the one area where you may see U.S. combat forces operating in the city” after June 30, the United States military’s top spokesman in Iraq, Maj. Gen. David Perkins, said in an interview.

In Baghdad, however, there are no plans to close the Camp Victory base complex, consisting of five bases housing more than 20,000 soldiers, many of them combat troops. Although Victory is only a 15 minute drive from the center of Baghdad and sprawls over both sides of the city’s boundary, Iraqi officials say they have agreed to consider it outside the city.
