On Saturday, Saudi Arabia announced it had executed 47 people in one day for terrorism offences, including the prominent Shia cleric Sheikh Nimr al-Nimr.
Most of those executed were Sunnis who were convicted of involvement in the deadly 2003 and 2004 al-Qaeda attacks.
Iran’s Supreme Leader, Ayatollah Ali Khamenei, described Nimr al-Nimr’s execution as a “political error”.
"The unjustly spilled blood of this oppressed martyr will no doubt soon show its effect and divine vengeance will befall Saudi politicians”.
"This oppressed cleric did not encourage people to join an armed movement, nor did he engage in secret plotting, and he only voiced public criticism ... based on religious fervour."
The announcement by the kingdom sparked protests around the world in the following 24 hours.
