A Syrian rebel commander has denied firing a chemical weapon in Aleppo, and has accused state forces for launching a scud missile with chemical agents.
"We were hearing reports from early this morning about a regime attack on Khan al-Assal, and we believe they fired a Scud with chemical agents.
Then suddenly we learned that the regime was turning these reports against us," said Qassim Saadeddine, a senior rebel and spokesman for the Higher Military Council in Aleppo.
"The rebels were not behind this attack" he said.
