Syria Announces it Will Sign Chemical Weapons Convention, Turn Over Chemical Weapons

Syrian President Bashar al-Assad said on Thursday that Syria will submit data on its chemical weapons 30 days after signing the Chemical Weapons Convention.

In Geneva, however, Secretary of State John Kerry rejected Assad's 30-day deadline for submitting weapons data, saying words are not enough.

In an interview, Syria confirmed its intention to place its weapons under international control, but said it made the decision in response to Russia’s proposal and not because of the threat of a U.S. military strike.

The United Nations said it received a document from Syria on Thursday about joining the Chemical Weapons Convention, a spokesperson said.

Obama Asks Congress to Delay Vote on Syria to Seek Diplomatic Solution

President Barack Obama told the nation in a special address Tuesday night that he is looking into a diplomatic plan to end a chemical weapons dispute in Syria.

Obama did say however, that he, as the Commander and Chief, reserves the right to use military force if necessary.

Much of the speech was a recap of what Obama has said in earlier addresses. That the U.S. has a reponsibity and that "tonight I want to talk to you about Syria -- why it matters, and where we go from here."

Although the President said that he was seeking a diplomatic solution, he was still pushing the idea of a "limited" military strike. Saying a strike against Assad would "send message no other nation could deliver."

Obama said that the military will hold its position, and will respond if a diplomatic path with Syria fails.

Syria Agrees to Hand Over Chemical Weapons to Russia

Syria announced on Tuesday that it is ready to disclose the location of its chemical weapons, stop production, and show its facilities to representatives of Russia, the United Nations, and other states.

President Barack Obama said that the plan could avert American strikes “if it’s real.”

Syria also said it is willing to join the Chemical Weapons Convention, Syrian Foreign Minister Walid Moallem said in a statement on Tuesday, according to Russian news agency Interfax.

Obama Wants to Delay Vote on Syria Strike

President Barack Obama told senators at luncheons on Capitol Hill today that he wants to delay a vote on authorizing force in Syria until a diplomatic solution has a chance to play out. Syria has accepted a Russian proposal to turn over all of its chemical weapons to international monitors.

Hillary Clinton Speaks Out on Syria for First Time

Hillary Clinton made her first public remarks in support of President Obama on Syria today, saying there needs to be a "strong response" from the international community to chemical weapons use, Politico is reporting. Her comments come following a week in which she spoke repeatedly with White House officials and made calls to two senators at the request of the administration.

Hillary Clinton said "The Assad regime's inhuman use of weapons of mass destruction ... violates a universal norm at the heart of our global order and therefore it demands a strong response form the international community," led by the United States. She said an offer by Russia to allow international inspectors into Syria to examine the country's chemical weapons stockpile is an important step but can't be an "excuse for delay or destruction."

Obama, Putin Clash at G20 Summit

Putin told reporters that the two listened to each other during the exchange, but that they didn't agree.

Both leaders said they could work together to seek a political solution to the Syrian conflict.

The two leaders hold opposing views over whether military action should be taken against the Syrian government over its alleged use of chemical weapons.

Syria Strike is One Step Closer

The Senate Foreign Relations Committee voted last week to allow President Obama the use of force against Syria.

However, before approving the resolution, amendments proposed by Sen. John McCain were adopted. The amendments made it clear that the end goal of conflict should be “a negotiated settlement that ends the conflict and leads to a democratic government in Syria.

The vote was 10-7.

House Committee Considers Syria Resolution

President Obama's call for missile strikes against Syria went before a House panel Wednesday. Obama wants congressional authorization for a limited military operation after more than a thousand people were killed in a suspected chemical weapons attack. Secretary of State John Kerry and Defense Secretary Chuck Hagel testified during the hearing of the House Foreign Affairs Committee.

Senate Resolution Would Limit Action to 90 Days

A new use-of-force resolution for Syria sets a 60-day deadline, with one 30-day extension possible, for President Barack Obama to launch military strikes against the regime of Syrian President Bashar Assad.

The proposal, drafted by Senators Robert Menendez (D-N.J.) and Bob Corker (R-Tenn.), the chairman and ranking member of the Senate Foreign Relations Committee, will also bar the involvement of U.S. ground forces in Syria.

The Foreign Relations Committee could vote on the Syria resolution as early as Wednesday. If accepted by that panel, Senate Majority Leader Harry Reid (D-Nev.) will schedule a full Senate vote for next week.

Secretary of State John Kerry Argues Case in Senate Hearing

Secretary of State John Kerry is making the case for lawmakers to support President Obama's request to authorize U.S. missile strikes against Syria.

Testifying during a Senate hearing on Tuesday, Kerry said the world is watching how the U.S. responds to a recent chemical weapons attack that killed more than a thousand people.  

"We now have learned that the hair and blood samples from first responders in East Damascus has tested positive for signatures of sarin," Kerry said.

He said the regime of Syrian President Bashar al-Assad must be held accountable.

Sen. Rand Paul, a Republican senator from Kentucky, seemed to be the most skeptical member at the hearing, saying he hoped Obama would abide by the will of Congress but is concerned he will not.

Paul sought to extract a pledge that the administration would not act if Congress votes down the use of military force in Syria.

The attack last month more than 1,000 people, including hundreds of children. President Obama is meeting with key lawmakers today to drum up congressional support for limited military strikes. Boehner says the behavior by the al-Assad regime will not be tolerated.

Israel Defense Ministry Tests Missile

The Israeli Defense Ministry says it carried out a successful test on a experimental target missile, in cooperation with the U.S. A statement posted on the ministry's Facebook page says the missile, called Anchor, was launched from a base in the central part of Israel last week. The posting says the launch was conducted in cooperation with the American Agency for Missile Defense, though U.S. officials stressed earlier today that U.S. forces were not involved in any launch.

The missile test sparked alarm after Russian news agency RIA reported a "ballistic" launch in the Mediterranean Sea. The two ballistic objects reportedly fell into the sea after traveling toward the east. Following the Russian report, U.S. officials said there had been no missile launches by American forces. Israel also denied any knowledge of a missile launch following the news agency report.
