Resumen de What chemical weapons have been used in Syria - if any?
The US has had a change of heart: its government is now reasonably confident that the Syrian military has used chemical weapons, specifically sarin. But things still don't add up. On 24 Apr, US defense secretary Chuck Hagel dismissed chemical weapons claims as "suspicions". However, on 25 Apr, in a letter to US senators, a White House spokesman said that US intelligence has decided "with varying degrees of confidence, that the Syrian regime has used chemical weapons on a small scale". Barack Obama has declared the use of chemical weapons a "red line" that would elicit a response by the US, potentially embroiling the country in Syria's civil conflict.
