A team of UN inspectors probing last week’s alleged chemical weapons attack in Damascus have now left the Syrian capital.
The experts have been investigating claims a toxic substance was used against rebels fighting the Assad regime.
Samples collected will now be analysed, but it is unclear how long it will take to reach any firm conclusions.
“The intention is of course to expedite the analysis of that sampling that’s been taken,” said
Martin Nesirky, a UN spokesman.
“But we have to be very clear here that before the mission can draw any conclusions about this incident, the evaluation of all available information including the laboratory analysis of all samples must be completed.”
The mission of the UN inspectors has been a difficult one. They have endured delays, heavy security and even snipers’ bullets.
Their inquiry will establish if a chemical attack took place, but will not determine who was responsible.
US Secretary of State John Kerry said on Friday that Syrian government forces killed 1,429 people in last week’s purported attack.
