The Syrian Foreign Ministry on Wednesday denied that the government forces are using chemical weapons during the ongoing battles in the country, media reports said.

The ministry statement denied accusations made recently in a report inquiry by the United Nations and the Organization for the Prohibition of Chemical Weapons (OPCW), which blamed the Syrian forces for carrying out a gas attack against rebels in Syria’s province of Idlib in March 2015, Xinhua news agency reported.

“The Syrian government, while denying all accusations in the report, stresses its commitment to all its pledges made when it joined the treaty of chemical weapons convention,” the statement said.

Chemical weapons are believed to have been used in several areas in the past years, with the government and the rebels trading accusations.

As many as 1,400 people were killed when several opposition-controlled areas in the suburbs around Damascus were struck by rockets containing the chemical agent sarin on August 21, 2013.

In the same year, a chemical attack hit the town of Khan al-Asal in Aleppo, in which several Syrian soldiers and civilians were killed. The government accused the rebels, who, in turn, denied the accusation.

In October 2013, OPCW officials arrived in Syria to monitor the dismantlement of the Syrian chemical weapons arsenal, after Damascus officially joined the Prohibition of Chemical Weapons Convention.

The OPCW later said the government has made its chemical weapon production facilities inoperable.
