This would force Obama to deepen his support for the rebels which is why I’m skeptical.

At least 635 people have been killed in a nerve gas attack on Syria’s Eastern Ghouta, activists at the Local Coordinating Committees told Al Arabiya on Wednesday morning. Other news sources cited lower numbers of deaths. Hundreds of others were reported wounded in the attack on rebel-held areas of eastern Damascus.

According to Al Arabiya, the activists at the Syrian Revolutionary Command Council said Syrian fighter planes were flying over the area after the bombardment. They accused the forces loyal to President Bashar al-Assad of using chemical agents.

The news coincides with a visit to Damascus by a United Nations team of chemical weapons experts.

Activists from the grassroots Local Coordination Committee initially reported at least 30 bodies had been brought to one field hospital in Kafr Batna neighborhood a few miles east of central Damascus.

Meanwhile, the Syrian Observatory for Human Rights said dozens of people were killed, including children, in a fierce bombardment.

Activists at the Local Coordinating Committees said Mouadamiya, southwest of the capital, came under the heaviest attack it had experienced since the start of the two-year-old civil war.

Update via Sky News:

More than 1,300 people have been killed in a chemical weapons attack near Damascus, according to Syria’s main opposition group.

The National Coalition claims toxic gas was used by President Bashar al Assad’s forces during a bombardment of rebel-held areas outside the Syrian capital.

It described the attack as a “coup de grace that kills all hopes for a political solution in Syria”.

Mohammed Saeed, an activist in the area, said hundreds of dead and injured have been taken to six make-shift hospitals in the eastern suburbs of Damascus.

“This is a massacre by chemical weapons,” he said via Skype. “The visit by the UN team is a joke…Bashar is using the weapons and telling the world that he does not care.”

Opposition groups said government forces had fired “rockets with poisonous gas heads” in the attack.
