Earlier, the Iranian government had summoned the Saudi ambassador to condemn al-Nimr’s execution. Saudi Arabia returned the slap, summoning the Iranian ambassador in Riyadh to vehemently object to Iran’s condemnation.

In Iran, the last word belongs to Supreme Leader Ayatollah Ali Khamenei. And on Sunday, he tweeted, “Doubtlessly, unfairly-spilled blood of oppressed martyr #SheikhNimr will affect rapidly & Divine revenge will seize Saudi politicians.”
