The United Nations mission investigating alleged use of chemical weapons in Syria on Friday continued working on a comprehensive report that it hopes will be ready by late October. The report is based on a number of allegations presented to the United Nations Secretary-General, of which seven have been found to warrant investigation according to the UN Secretary-General's Mechanism for investigation of alleged use of chemical and biological weapons.

The probed allegations related to the following seven reported incidents:
Khan al-Assal, 19 March 2013
Sheikh Maqsoud, 13 April 2013
Saraqeb, 29 April 2013
Ghouta, 21 August 2013
Bahhariyeh, 22 August 2013
Jobar, 24 August 2013
Ashrafiah Sahnaya, 25 August 2013.     

The continued activity uses the same impartial fact-finding modalities and techniques applied to the first conducted round of investigations. This means using scientifically agreed and accredited environmental and epidemiological methods such as sampling and laboratory analyses as well as interviews with physicians, victims and parties connected to the incidents, said the team’s leader professor Åke Sellström.

The UN team of investigators, which returned to Syria for a second working visit on 25th September, expects to finalize its activities in the country by Monday, 30th September. In the course of performing their task, the experts have received several documents and samples and have conducted many interviews.

The team, led by Dr. Sellström, is composed of experts and specialists from the Organization for the Prohibition of Chemical Weapons (OPCW) and the World Health Organization (WHO).
