Chemical weapons were probably used five times during the Syrian conflict, according to a report by UN inspectors. The report cites "credible evidence" and "evidence consistent with the probable use of chemical weapons" that appear to prove the use of such weapons in Ghouta, Khan Al Asal, Jobar, Saraqueb and Ashrafieh Sahnaya. However, the UN said it cannot corroborate their use in Bahhariyeh and Sheik Maqsood.
