Saudi Arabia on Friday blacklisted the Muslim Brotherhood as a terrorist organization, along with three other Middle East-based Islamist groups, Al Arabiya News Channel reported, citing a royal decree.
The Saudi terrorism list also includes the kingdom’s branch of the Shiite movement Hezbollah and Syria-based militant groups the Islamic State of Iraq and Syria (ISIS) and the al-Qaeda linked al-Nusra Front.
Hundreds of Saudi fighters are believed to have joined ISIS and al-Nusra in Syria.
The royal decree gives fighters a 15-day ultimatum to return home. The declaration came after King Abdullah announced on Feb. 3 tough penalties for activities deemed as terrorism.
