Syria has denied ever using chemical weapons during the civil war, AFP just reported.
There are numerous accusations that Syrian President Bashar al-Assad's government has used chemical weapons, including in a large-scale attack in August 2013. Damascus has always denied the allegations.
Russia is to ban imports of agricultural products, including fruit and vegetables, from Turkey, but there is as yet no restriction on manufactured goods, First Deputy Prime Minister Igor Shuvalov said at a government meeting today.
The list of banned goods consists of items that are not critically important for the Russian economy, Shuvalov added.
Russian Prime Minister Dmitry Medvedev has said that Turkish business has "become a hostage of the politics of its country's leadership."
Medvedev's comments came as Russia's government announced this morning that Moscow is to ban imports of mainly agricultural products from Turkey, in response to the downing of a Russian jet near the Syrian border last week.
AFP's Jo Biddle tweets this on Syria's comments denying chemical weapons use at a meeting of the Organization for the Prohibition of Chemical Weapons (OPCW) in the Hague today.
Russian economic restrictions against Turkey are just a "first step" and the list of banned goods could be expanded if required, Russian Prime Minister Dmitry Medvedev announced.
Medvedev said that the economic restrictions must be carried out in a pragmatic manner, to maximize the effect in Turkey while causing minimum damage to Russia.
The economic restrictions were a "neccessary response to the aggressive and unfriendly actions of Turkey," Medvedev was quoted as saying.
The British government's official anti-IS Twitter account has tweeted that Turkey has a right to protect its air space.
A European Union envoy has criticized Syria for "gaps and contradictions" in its declarations about its chemical weapons arsenal to the Organization for the Prohibition of Chemical Weapons (OPCW), AP reports.
Jacek Bylica of Luxembourg said that lack of clarity from Damascus, "make it impossible to have confidence that its chemical weapons program has been irreversibly dismantled."
The OPCW has a special team reviewing Syria's declarations amid fears that the chemical weapons could fall into the hands of the IS group or other militant groups in Syria.
