Saudi Arabia severed ties with Iran following protests over the execution of Shiite cleric Sheikh Nimr al-Nimr.
Riyadh expelled Iran’s diplomats on Jan. 3, citing attacks on the Saudi Embassy in Tehran in which protesters set part of the building on fire. Saudi ally Bahrain followed suit in cutting off relations on Jan. 4 as did Sudan. The United Arab Emirates has downgraded ties.
It is not known how far tensions will spiral out of control. Saudi Arabia and Iran back opposite sides in the wars in Syria and Yemen and also have very different attitudes on Iraq, where Iran funds, arms and trains Shiite militias, which have been accused of sectarian atrocities against Sunnis.
It is important to remember both Saudi Arabia and Iran are states which implement sharia as state law. Both carry out executions of gays, alleged blasphemers and adulterers. Both implement strict dress codes for women and enforce them with roaming bands of morality police.
