Hundreds of civilians died Wednesday in an attack on a neighborhood outside the Syrian capitol of Damascus. Opposition forces trying to take down President Bashar al-Assad say the government used chemical weapons to attack its own people.
On Thursday, Syrian opposition forces claim the government bombed the same rebel held suburbs of Damascus where an alleged chemical weapons attack took place Wednesday.
Rebels say chemical weapons killed as many as 1,300 people. Images posted to Youtube showed men, women and children either dying or already dead. CBS news can not confirm the videos, but experts say they appear to support the opposition's claims.
"These people have died from some unconventional weapon. And at the moment, the most likely explanation would be some sort of chemical weapon," said chemical weapons expert Hamish de Bretton-Gordon.
The U.N. security council held an emergency meeting Wednesday night. The council says it wants answers as to how so many people were killed.
A team of U.N. inspectors are already in Syria to investigate past claims of chemical weapons use. Now they want to go to the site of Wednesday's alleged attack.
