Moscow has submitted data on Turkey’s illegal arms and military hardware supply to ISIL in Syria to the UN Security Council.

Supplies are supervised by the Turkish intelligence service, Russian UN envoy Vitaly Churkin said as cited by Russian media.

The main supplier of arms and military equipment to ISIL militants is Turkey, which uses non-governmental organizations (NGOs) for this purpose.

The National Intelligence Organization of Turkey is in charge of the operations.

Transportation is carried out mainly via automobiles, including humanitarian aid convoys, Churkin wrote in a letter to the UN Security Council (UNSC).

Terrorist groups operating in Syria received explosive materials worth $ 1.9 million via Turkey last year, according to the letter.

In total, the terrorists were delivered 2.5 thousand tons of ammonium nitrate (worth around $788,700), 456 tons of potassium nitrate ($468,700), 75 tons of aluminum powder ($496,500), sodium nitrate ($19,400), glycerin ($102,500) and nitric acid ($34,000 thousand) via Turkey in 2015, Churkin wrote.
