Protests have begun in Iran following an announcement that a Shia cleric was among those executed in Saudi Arabia.
Saudi Arabia executed 47 people, including Sheikh Nimr al-Nimr, a prominent cleric.
Several Al Qaeda fighters were also executed as Saudi Arabia disclosed that they had carried out terrorist acts against the state.
The protests have been broken up in Iran as concerns continue over a possible backlash over the execution of Sheikh Nimr.
