Iran's Supreme Leader says Saudi Arabia will face "divine revenge" after the execution of a revered Shiite cleric.

Ayatollah Ali Khamenei made the comments Sunday, a day after Riyadh announced the execution of Sheikh Nimr al-Nimr.

Khamenei's website carried the comments by the ayatollah, who also criticized the ongoing Saudi-led war in Yemen against Shiite rebels, as well as the "persecution" of Shiites living in Saudi-allied Bahrain.

Also on Sunday, Khamenei's Twitter account said: "Doubtlessly, unfairly spilled blood of oppressed martyr (hashtag)SheikhNimr will affect rapidly & Divine revenge will seize Saudi politicians."

Saudi Arabia says that by condemning the execution of an opposition Shiite cleric, Iran has "revealed its true face represented in support for terrorism."

A Foreign Ministry statement carried by the official Saudi Press Agency accuses Tehran of "blind sectarianism" and says that "by its defense of terrorist acts" Iran is a "partner in their crimes in the entire region."

Shiite-majority Iran expressed outrage over the execution of Sheikh Nimr al-Nimr, who was put to death along with 46 others convicted of terrorism charges, including three other Shiite dissidents and a number of al-Qaida militants.

Al-Nimr was a central figure in protests by Saudi Arabia's Shiite minority until his arrest in 2012. He was critical of the Saudi government and but denied ever advocating violence.
