Syria Situation a "Challenge to the World," Says Obama

Trying to rally support

President Barack Obama called Syria's chemical weapons attack "a challenge to the world" and said he is considering a "limited, narrow act" against the county's regime.

"We're not considering any open-ended commitment," Obama told reporters at the White House Friday afternoon. "We're not considering any boots on the ground approach."

"I have not made any decisions about the various actions that might be taken," Obama said. "We have consulted with allies. We have consulted with Congress."
