After demonstrators stormed Saudi Arabia’s Tehran embassy, Foreign Minister Adel al-Jubeir announced the severing of dgimplatic ties with Iran. Adel al-Jubeir expelled Iranian diplomats, giving them forty-eight hours to evacuate the country.

Saudi Arabia’s execution of top Shia cleric, Sheikh Nimr al-Nimr, along with forty-six other individuals found guilty of terrorism lead to protests across the region and beyond.

The BBC reports:

Saudi Foreign Minister Adel al-Jubeir was speaking after demonstrators had stormed the Saudi embassy in Tehran.

Sheikh Nimr al-Nimr and 46 others were executed on Saturday. Saudi Arabia found them guilty of “terrorism”.

Mr Jubeir said that all Iranian diplomats must leave Saudi Arabia within 48 hours.

Saudi Arabia has evacuated its diplomats from Tehran, Dubai-based al-Arabiya TV reports.

Earlier, Iran’s Supreme Leader Ayatollah Ali Khamenei warned that the Sunni Muslim kingdom would face “divine revenge” for the execution – an act which also angered Shia Muslims elsewhere in the Middle East.

Ayatollah Khamenei called Sheikh Nimr a “martyr” who had acted peacefully.

Protesters stormed the Saudi embassy in Tehran late on Saturday, setting fire to the building before being driven back by police.

Iran is Saudi Arabia’s main regional rival – they back opposing sides in the Syria and Yemen conflicts.

Yahoo News explains further:

On Saturday, a mob attacked the Saudi embassy in Tehran and a consulate in second city Mashhad amid protests at the execution in Saudi Arabia of Sheikh Nimr al-Nimr.

The 56-year-old, a force behind 2011 anti-government protests in eastern Saudi Arabia, was among 47 convicted men put to death on Saturday in the kingdom.

The others were Shiite activists and Sunnis who the Saudi interior ministry said were involved in Al-Qaeda attacks, with some beheaded and others shot by firing squad.

Iran arrested 44 people over the embassy assault, which President Hassan Rouhani described as “totally unjustifiable”.

But the Islamic republic’s supreme leader Ayatollah Ali Khamenei condemned Nimr’s execution, saying “God will not forgive” Saudi Arabia for putting him to death.

Jubeir responded on Sunday by saying: “Iran’s history is full of negative interference and hostility in Arab issues, and it is always accompanied by destruction.”

Relations between Sunni-ruled Saudi Arabia and Shiite-ruled Iran have been strained for decades, with Riyadh frequently accusing Tehran of interfering in Arab affairs.
