SYRIAN Deputy Foreign Minister Bashar Jaafari claimed that the Turkish President Recep Tayyip Erdogan’s son was involved in stealing the country’s oil and colluding with Isis on Thursday.

Mr Jaafari also said that the Turkish state and intelligence services had been sending weapons to jihadist groups including al-Nusra via the shady Sadat private security company, whose founder Adnan Tanriverdi is an adviser to Mr Erdogan.

The Syrian official was confirming allegations made by Turkish mafia boss Sedat Peker, whose weekly YouTube videos have gripped the nation as he reveals dark secrets about the country’s leading politicians.

The exiled mobster said in an instalment released on May 30 that billions in the illicit oil trade was being organised by Turkey’s director of presidential administrative affairs Metin Kiratli and that Sadat had been providing arms to “terror groups.”

In an interview with the German media organisation Deutsche Welle on Thursday Mr Jaafri said that the Syrian government has sent 108 letters to UN secretary-general Antonio Guterres and other bodies about “thousands of terrorists coming in from Turkey.”

“I’d like to express that I confirm, affirm and verify what Mr Sedat Peker said is completely true,” he said.

“What Mr Sedat Peker said about the involvement of the Erdogan regime — including his family members — in the theft of our oil, natural gas, mines and grain,” Mr Jaafari added.

“Because we witnessed in 2015 and 2016 that Erdogan’s son managed the theft of our oil and natural gas by Isis.”

The Syrian official also claimed that Turkish intelligence agent Heysem al-Kassar, who died in a suspicious road accident in February, smuggled two litres of sarin gas into Syria under the guise of humanitarian aid.

The chemical agent was given to al-Nusra, which used the chemical agent to carry out an attack killing Syrian soldiers and civilians in Aleppo.
