I covered it at the time in the post, German Intelligence Warns – Saudi Arabia to Play "Destabilizing Role" in the Middle East. Here's an excerpt:

Saudi Arabia is at risk of becoming a major destabilizing influence in the Arab world, German intelligence has warned.

Internal power struggles and the desire to emerge as the leading Arab power threaten to make the key Western ally a source of instability, according to the BND intelligence service.

"The current cautious diplomatic stance of senior members of the Saudi royal family will be replaced by an impulsive intervention policy," a BND memo widely distributed to the German press reads.

Saudi Arabia has previously been accused of supplying arms and funding to jihadist groups fighting in Syria, including Islamic State in Iraq and the Levant (Isil).
