Assad: Syria to offer data on chemical weapons one month after signing convention

Syrian President Bashar Assad

Last Updated 2:10 p.m. ET

BEIRUT President Bashar Assad says Syria will start submitting data on its chemical weapons stockpile a month after signing the convention banning such weapons. Meanwhile, the United Nations said it has received a letter from Syria stating its intention to join the chemical weapons treaty which bans the production, stockpiling and use of the deadly weapons.

Assad says submitting the data a month after signing the convention is the "standard process" and his country will follow it.

He made the comment in an interview with Russia's Rossiya-24 TV. The full interview will be broadcast later Thursday.

However, speaking in Geneva, U.S. Secretary of State John Kerry rejected Assad's suggestion that a 30-day delay is "standard."

"There is nothing standard about this process," Kerry said, because Assad has used his chemical weapons. "The words of the Syrian regime in our judgment are simply not enough."

At a news conference with Russian Foreign Minister Sergey Lavrov, Kerry cautioned that a U.S. military strike could occur if Assad doesn't agree to dismantle his chemical arsenal properly.

"There ought to be consequences if it doesn't take place," Kerry said.

Lavrov said the dismantling "will make unnecessary any strike against the Syrian Arab Republic."

Assad said today that the process is "two-sided" and suggested it will only work if the U.S. halts its threats of military action against Syria.

The U. N. Secretary General, Ban Ki-moon received a letter from the Syrian Mission to the United Nations in New York, confirming that Syria has acceded to the Convention on Chemical Weapons, reports CBS News' Pamela Falk, who was shown the letter.

The letter is in the process of being translated, U.N. associate spokesman Farhan Haq said Thursday — two days after Syria announced that it was prepared to sign the international treaty it long has rejected.

The Chemical Weapons Convention bans the development, production, stockpiling and use of chemical weapons. The convention requires all parties to the treaty to declare and destroy whatever chemical weapons they may possess.

Meanwhile, President Barack Obama says he is hopeful Secretary Kerry's meetings with Lavrovcan "yield a concrete result" on Syria.

Kerry opened two days of meeting with his Russian counterpart in Geneva Thursday. The two hope to settle on the outlines of a plan to secure and destroy Syrian chemical weapons stockpiles.

CBS News correspondent Margaret Brennan reports that Kerry brought a team of about 30 arms control experts and diplomats to meet tonight with a similarly-large Russian delegation. They expect at least two days of very technical, intense talks.

Mr. Obama made his remarks at the beginning of a Cabinet meeting at the White House. The U.S.-Russia talks offer a potential path to avoid U.S. strikes against the Syrian government for an alleged chemical attack on civilians last month that the U.S. blames on Syrian President Bashar Assad.

A senior Obama administration official reacting Thursday to an op-ed by Vladimir Putin, in which the Russian leader claims millions around the world increasingly see America not as a model for democracy, but as relying solely on brute force to intervene in foreign conflicts, said the onus was now on Russia to prove it's credentials at peacemaking.

"President Putin has invested his credibility in transferring Assad's chemical weapons to international control, and ultimately destroying them," said the official. "The world will note whether Russia can follow through on that commitment."

On Thursday, Syria's top rebel commander called for regime officials to be put on trial for carrying out the alleged chemical attack near Damascus that killed hundreds last month, blasting the Russian proposal for securing the country's chemical arsenal.

The comments by the head of the Free Syrian Army came as Assad told Russian state television his government agreed to surrender its chemical weapons in response to Russia's initiative and not because of a threatened U.S. attack.

Gen. Salim Idris' statement was broadcast on pan-Arab satellite channels hours before talks in Geneva between U.S. Secretary of State John Kerry and Russian Foreign Minister Sergey Lavrov on the Russian proposal.

"We call upon the international community, not only to withdraw the chemical weapons, that were the tool of the crime, but to hold accountable those who committed the crime in front of the International Criminal Court," Idris said.

He added that the FSA "categorically rejects the Russian initiative" as falling short of the expectations of rebel fighters.

The U.S. accuses Assad's government of being behind the Aug. 21 attack in the suburb of Ghouta, which the U.S. says killed 1,429 people. Other estimates of the deaths are lower.

Assad has denied responsibility and accuses U.S. officials of spreading lies without providing evidence.

The Russian proposal has, at least for the moment, averted the threat of U.S. military action against Syria. Many rebels had held out hopes that U.S.-led punitive strikes on Assad's forces would help tip the scales in their favor in Syria's civil war, which has claimed over 100,000 lives so far.

In an interview set to be broadcast Thursday, Assad told Russia's state Rossiya 24 news that "Syria is transferring chemical weapons under international control because of Russia."

Assad added that "the U.S. threats hadn't influenced" his government's decision.

Syria's Deputy Prime Minister Qadri Jamil suggested on Thursday that the Russian proposal will only succeed if the United States and its allies pledge not to attack Syria in the future.

"We want a pledge that neither it (the U.S.) nor anyone else will launch an aggression against Syria," Jamil told The Associated Press in Damascus. He did not elaborate. Jamil was responding to a question on his expectations from the meeting Thursday between Kerry and Lavrov.

Kerry and a team of U.S. experts will have at least two days of meetings with their Russian counterparts in Geneva. They hope to emerge with an outline of how some 1,000 tons of chemical weapons stocks and precursor materials as well as potential delivery systems can be safely inventoried and isolated under international control in an active war zone and then destroyed.

Officials with Kerry said they would be looking for a rapid agreement on principles for the process with Russians, including a demand for a speedy Syrian accounting of their stockpiles.

In Washington, officials said the CIA has been delivering light machine guns and other small arms to Syrian rebels for several weeks, following President Barack Obama's decision to arm the rebels.

The agency also has arranged for the Syrian opposition to receive anti-tank weapons like rocket-propelled grenades through a third party, presumably one of the Gulf countries that has been arming the rebels, a senior U.S. intelligence official and two former intelligence officials said Thursday. They spoke on condition of anonymity because they were not authorized to discuss the classified program publicly.

Loay al-Mikdad, a Free Syrian Army spokesman, told the AP that they have not received any weapons from the U.S. although they expect that in the near future.

Meanwhile, the Syrian Observatory for Human Rights said rebels fighting Assad's forces captured Thursday the village of Imm al-Lokas in the southern region of Quneitra near Syria's Israeli-occupied Golan Heights.

The Britain-based activist group added that rebels also captured several army posts in the area in heavy fighting that caused casualties on both sides.

It also said that in the northeastern province of Hassakeh, clashes between Kurdish fighters and members of the al-Qaida-linked Nusra Front and the Islamic State in Iraq and the Levant in the past two days killed 13 Kurdish gunmen and 35 militants.

The two sides have been fighting in northern Syria for months in clashes that left scores of people dead on both sides.

Syrian state media said government troops advanced in the predominantly Christian village of Maaloula near Damascus, capturing the main square as well as the Mar Takla convent where several nuns were staying.

A resident in the village told the AP that troops were trying to capture a rebel-held hotel on a hill overlooking the area. The man, who spoke on condition of anonymity for fear of reprisals, said most of the fighting Thursday was taking place in the western part of the village.

Government troops are trying to flush out rebel units, including two linked to al-Qaida, from the hilltop enclave the rebels broke into last week.

Most of the village's 3,300 residents have fled to safer parts of the country, although some have remained, hunkering down in their homes, activists said.

Maaloula, about 60 kilometers (40 miles) northeast of Damascus, had until recently been firmly in the regime's grip despite being surrounded by rebel-held territory. The village was a major tourist attraction before the civil war. Some of its residents still speak a version of Aramaic, a biblical language believed to have been used by Jesus.
