Syrian authorities said the rebels had carried out the chemical weapons attack
The US said that its assessment of the Syrian situation is based on inputs given by medical personnel, witnesses, journalists and other sources. UN chemical weapons inspectors are also invstigating the alleged chemical weapons attacks and are set to submit reports to the UN after they leave Syria on Saturday.
Kerry, however, said Washington already had the findings and there was nothing fresh to learn about.
