Amateur video cannot independently verify shows people struggling to breath following an alleged gas attack in a rebel-held village in Hama province.

Now, rebel fighters and the Syrian government blame each other for the purported chemical attack, that both sides say injured at least 100 people.

State media accuses the al-Qaeda linked group Nusra Front.

Opposition activists say forces loyal to President Bashar al-Assad carried out the attack.
