Saudi Foreign Minister Adel al-Jubeir said his country is kicking out Iranian politicians and severing ties with Iran amid rapidly rising tensions between the two nations following the Saudi execution of a Shiite Islam cleric popular in Iran.
Iranian diplomats have two days to leave Saudi Arabia, and Saudi diplomats in Iran have been told to come home, according to al-Jubeir.
The Saudi government executed Saudi Sheikh Nimr al-Nimr along with 46 others on Saturday in a series of executions that took place across the country.
Al-Nimr was convicted of terrorism, though his family and others say he was only an outspoken, peaceful demonstrator. He was at the center of Saudi Arabia's Arab spring protests, which took place in 2011.
Saudi shiites protested al-Nimr's arrest in 2012, and again protested when he was sentenced to death in 2014.
Iranian protesters attacked and set fire to the Saudi embassy on Saturday after news of the execution spread.
Iranian officials renamed the Saudi embassy street after al-Nimr, and Iran's Ayatollah Ali Khamenei said Saudi politicians will face "divine revenge" for the execution.
This diplomatic row is the latest in the often-conflicted relationship between Iran and Saudi Arabia. Much of the conflict in their relationship stems from the religious makeup of the two nations. Iran is majority-Shiite Muslim, while Saudi Arabia is majority Sunni.
