Syria: Who wants what after chemical weapons horror

 

(CNN) -- The ripple effects of an alleged chemical attack in Syria are being felt across the globe. The rhetoric is ratcheting up with talk of punishing Syria, even though Syria denies using chemical weapons. Allies of President Bashar al-Assad accuse the rebel forces of carrying out the chemical strike.

Meanwhile rebel forces, who also deny responsibility for the strike, say 1,300 people died in the attacks on the outskirts of Damascus. CNN correspondents and experts explain the different positions of some key nations involved in preparing for -- or warning against -- international military attacks on Syria.
