News portal Spiegel Online said the report, marked “classified”, pointed to close military ties between Damascus and Tehran beyond the deployment of Iran-backed Hezbollah militia on the side of regime forces.
The German intelligence paper reportedly said Iran had also sent elite troops from its Revolutionary Guard to support the forces of Syrian President Bashar al-Assad.
The intelligence report also said a source had reported that a Syria-Iran military deal from November 2012 allowed Assad “to station large parts of his air force on safe Iranian territory and to use them when needed,” said Spiegel Online.
