According to the chemical weapons inspectors, the photographs and videos provided by the Syrian government showed an empty building "with extensive battled damage."
The facility is supposedly located near the city of Aleppo. The images were further tagged to verify the exact location and time of documentation in order to authenticate the evidence.
OPCW has accepted the Syrian documentation as legitimate, which means that 22 of the 23 declared chemical weapons sites in Syria have been dismantled.
OPCW inspectors visited 21 of the 23 sites last month, but we unable to visit the remaining two, including the Aleppo site, due to security concerns.
