President Barack Obama on Saturday backed away from an imminent military strike against Syria to seek the approval of the U.S. Congress, in a decision that likely delays U.S. action for at least 10 days.

The announcement came after the United Nations experts investigating last week's alleged chemical weapons strike outside Damascus left Syria. The inspectors' departure appeared to signal a looming confrontation between the U.S. and President Bashar Assad's regime, although the UN vehemently denied that it was somehow stepping aside to allow U.S. intervention.
