We're going to wrap up our live blog coverage for the day. Here's a summary of where things stand:

• The Senate foreign relations committee approved an authorization of the use of military force in Syria by a vote of 10-7-1. The resolution now goes to a full Senate vote. The committee inserted language making it "the policy of the United States to change the momentum on the battlefield in Syria."

• That seemed to go beyond the "limited" strikes proposed by the president. But Senator John McCain, the author of the amendment, claimed the White House backed the added language.

• Syrian state media denied a Reuters report that former defense minister Ali Habib, an Alawite who has been personally close to Assad, has defected. Reuters stood by its report.

• President Obama called for international support for military action in Syria at a news conference in Stockholm. He was en route to the G20 summit in St. Petersburg, which runs Thursday-Friday.

• Russian president Vladimir Putin said strikes on Syria would amount to "aggression" if not backed by a UN resolution. Putin claimed he might back such a resolution if conclusive evidence emerged of a chemical weapons attack carried out by the regime.

• President Obama said "We've hit a wall in progress on the Russian relationship" but said he was "always hopeful" Putin would change his mind.

• The French parliament debated a use of force in Syria, although no vote on a war resolution was scheduled and President Hollande does not need parliament to act.

And from the House hearing on the administration's Syria policy:

• Kerry gave an estimate of the extremist element among the opposition that seemed larger than previous estimates. "Bad guys" make up 15-25% of the opposition, he said, out of 70,000-100,000 total. On Tuesday Kerry said the opposition is growing more moderate.

• Kerry said the US was not acting as the world's policeman but it does have great power and as a consequence extra responsibility.

• Hagel emphasized the complexity of the situation: "This is an imperfect situation," he said. "There are no good options here... "This is unpredictable, it's complicated, it's dangerous."

• Kerry said it's "100%" likely Assad will use chemical weapons routinely unless Congress endorses a strike on Syria.

• Kerry said America's security has been directly threatened: "Our security interests are directly involved in what is happening in the Middle East. Our security interests are directly threatened."

• Kerry continued to assert that the proposal on the table does not involve "war." "I don't believe we're going to war. I just don't believe that," he said.
