The Calliope* Crashed to the Ground.

In Britain, an anti-regime monitor of the fighting in Syria says it has been compiling a list of the names of the dead from the Aug. 21 attack and that its toll has reached 502. The Obama administration reported 1,429 people died, including 426 children, citing intelligence reports. The Assad government blames opposition forces for the deaths.

The DVD compilation of videos of victims of the gas attack near Damascus was shown to senators during a classified briefing on Thursday, and some of the videos were first broadcast Saturday on CNN. Supporters of the Syrian rebels had posted the videos on YouTube.

Senate Intelligence Committee Chairman Dianne Feinstein of California requested the material from the CIA, and members of her committee watched the videos on Thursday. The DVD is a compilation of footage of victims of the Aug. 21 chemical weapons attack in the suburbs of the Syrian capital of Damasacus that were posted on YouTube by supporters of the Syrian rebels.

The U.S. official, who was granted anonymity to discuss the subject of a classified briefing, said the videos were also referenced in the government's four-page intelligence assessment, released last week, that blamed the Syrian government for the chemical attack.

Doctors without Borders, I think I read, confirmed treating/seeing  around 365 dead gassed victims, not the ... 1429 our administration is currently reporting.

Not too precise with time or numbers, this group.  Boy, those videos sure are emotional, though...

Democratic congressional aides said Obama's planned speech to the nation on Tuesday and briefings that top members of Obama's national security team will give to the entire House on Monday would prove pivotal in the thinking of many lawmakers.
