Saudi Arabia executed 47 prisoners on Saturday, including Sheikh Nimr.
Among them were four Shias accused of anti-government protests in recent years.
The executions took place in 12 cities in Saudi Arabia, four prisons using firing squads and the others beheading. The bodies were then hanged from gibbets in the most severe form of punishment available in the kingdom’s law.
Larijani in a message condemned the Saudi move and described it as an inhumane measure that runs counter to human rights and freedom of speech and one that would hurt the feelings of Muslims all over the world.
He said the Riyadh regime’s act of imprudence would intensify tension in the region and that only benefits terrorists.
The execution of Sheikh Nimr has drawn widespread condemnation from all over the world.
