The paper claims that using these photographs, Bulgarian authorities have managed to uncover an illegal supply route for diesel and gasoline through the ports of Varna and Burgas.
"We can announce information once the investigation is closed. There are still ongoing procedures. But still, at this point, there are no such indications [of illegal oil supply routes through Bulgarian ports]," the press officer said.
Bulgarian security forces have started a large-scale inspection of gas stations throughout the country, with over 50 facilities being monitored.
The jihadist group, outlawed in Russia and many other countries, controls large swaths of land in oil-rich Syria and Iraq. In late 2015, the Russian Defense Ministry presented evidence showing that Daesh had been smuggling oil across the Syrian-Turkish border in large volumes.
According to Russian envoy to the United Nations Vitaly Churkin, illicit exports of Daesh's oil, primary via Turkey, allows the group, on average, to generate approximately $1.5 million in revenue every day.
