Foreign-sponsored militants in Syria have executed 51 civilians in Khan al-Assal, a strategic town close to the northern city of Aleppo.
Reports said on Friday that the civilians were killed on Monday after the town fell to the militants. The victims were all shot in the head.
A number of military personnel were also summarily executed in addition to the civilians, according to the reports.
Most of the town is currently under the control of the militants. Khan al-Assal was the location of a chemical attack earlier this year that left 30 people dead.
On July 9, the Russian ambassador to the United Nations said that Russian experts collected samples at the site of the attack in the town.
The samples were examined at a laboratory in Russia which is certified by the Organization for the Prohibition of Chemical Weapons (OPCW), and the results of the analysis prove that a missile fired by the militants was filled with sarin, Ambassador Vitaly Churkin stated.
Britain, France, and the United States have accused the Syrian government of using chemical weapons. Damascus has denied the charges, saying it was actually the militants who used chemical weapons on several occasions.
On June 15, Russian Foreign Minister Sergei Lavrov said the materials collected by the US government allegedly proving that Syrian troops used chemical weapons would not meet the requirements of the Hague-based OPCW.
Syria has been gripped by deadly unrest since 2011. According to the United Nations, more than 100,000 people have been killed and millions of others displaced in the violence.
