Key Takeaways:

1. Iranian Supreme Leader Ayatollah Ali Khamenei conditionally approved the implementation of the nuclear deal in an open letter to President Hassan Rouhani on October 21. His approval will likely end domestic debate over whether Iran should reject the deal before a violation by other parties.
2. Yemeni stakeholders agreed to resume talks under UN auspices, but the conflict on the ground continues unabated. There will be an initial round of talks held in Riyadh, Saudi Arabia with Abdu Rabbu Mansour Hadi’s government and in Muscat, Oman with the al Houthis, before both sides come together.
3. An al Shabaab religious leader based in Puntland publicly pledged allegiance to the Islamic State in Iraq and al Sham (ISIS), sparking a round of internal al Shabaab arrests as the group attempts to limit ISIS’s influence in Somalia. Al Shabaab has actively sought to maintain a cohesive front against ISIS outreach.
