Isis oil going to Assad, Turkey: US Treasury Department official Adam Szubin said the Islamic State (Isis) was selling much of its oil to Syrian President Bashar al-Assad, while some was also reaching Turkey.

The US statement that some amount of Isis oil, the terror group's chief source of income, was going to Turkey from its border with Syria comes after Russia accused Turkish President Tayyip Erdogan and his family of being involved in oil trade with Daesh. 

Isis has made more than $500 million from its oil trade, the US official said on Thursday, according to Reuters. 

Isis prints passports to help jihadists enter America: The US Homeland Security Investigations (HSI) has warned that Isis may be printing authentic-looking Syrian passports ever since it captured the city of Deir ez-Zour, which houses a passport office. 

The agency said in its intelligence report Isis may be using the passport-printing machines to make fake passports that may have helped its fighters and supporters enter the United States. 

"Since more than 17 months [have] passed since Raqqa and Deir ez-Zour fell to ISIS, it is possible that individuals from Syria with passports 'issued' in these Isis-controlled cities or who had passport blanks, may have travelled to the US,"  the HSI Intelligence Report says, according to ABC News
