Troop Withdrawal From Iraq

Thousands of American troops are on their way home.

The last American combat brigade in Iraq has left the country.

The soldiers packed up and rolled into Kuwait early Thursday morning, seven years after the U.S. invasion began.

But operation Iraqi Freedom isn't quite over. The Pentagon says another 6,000 combat troops won't leave until the end of the month, and the 50,000 non-combat troops will stay until next year.

"Our commitment in Iraq is changing from a military effort led by troops to a civilian effort led by our diplomats," President Obama said.

What officials are worried about is the stability of the Iraqi government one the U.S. leaves.

On Monday a suicide blast at military recruitment center killed 61 people, injuring more than 100 other.
