A group of UN experts has returned to Syrian in order to continue a chemical weapons probe. The experts investigated the chemical attacks on Aleppo, Idlib and Damascus in late August and left the country in order to prepare an official report.
The experts have already confirmed that poisonous gases had indeed been used in Syria, but haven't managed to find out who was responsible for the attacks.
The head of the group, Swedish Professor Oke Selstrom, says the final report may be presented at the end of October.
