"Turkey represents a key ally in the Middle East," Panetta told reporters traveling with him.
He added that in addition to being a strong NATO ally, Turkey is extremely important to the ability to try to keep what is happening in the Middle East headed in the right direction.

The secretary also underlined that Turkey has taken a strong position in condemning Syria's violent crackdown on protestors and calling for President Bashar al-Assad to step down.
