UPDATE 1:51 p.m.: President Barack Obama said in a news conference Friday afternoon there are no plans to send troops on the ground to Syria. However, he said a "limited, narrow act" is being considered.
WASHINGTON (CNN)- After a U.N report says investigators found evidence of chemical weapons used by the Syrian government against rebels, all eyes are focused on the response by the United States.
U.N. officials began leaving the region Friday after days of investigating the use of chemical weapons.
A preliminary U.S. government assessment of the Syrian situation determined that 1,429 people were killed on August 21 in an attack that investigators believe was carried out by the Syrian government.
The White House has made it clear that the United States will respond in some way to the use of chemical weapons.
Earlier this week, officials announced that the military will not send U.S. troops on the ground.
Secretary of State John Kerry reiterated that point on Friday afternoon during a news conference.
He said the response "will not involve boots on the ground."
Kerry also announced that the U.S is "not alone in our will to do something about" last week's chemical weapons attack in Syria.
He also stressed the United States will not repeat justifying a military campaign on false intelligence, referring to the war in Iraq.
Despite working toward leaving the Middle East, Kerry said, "Fatigue does not absolve us of our responsibility. Just longing for peace does not necessarily bring it about."
