US adding troops in Iraq to aid Sunni integration

Move won't place advisers closer to front lines of war

Amid persistent setbacks in the fight against Islamic State. US President Barack Obama turned his military's focus to the Sunni-Shiite divide, ordering hundreds of troops to Iraq to better integrate Iraqi forces and lay the groundwork to retake Ramadi and other key cities.

The expanded military campaign will set up a new base in Anbar province to advise Iraqi forces on how to plan and organize operations and help them reach out to Sunni tribes and bring them into the battle.
