Speaking at a press conference on Sunday, Foreign Minister Adel al-Jubeir demanded that the Iranian diplomatic mission and related entities leave the country within 48 hours.
He said Riyadh would not allow the Islamic Republic to undermine the Sunni kingdom’s security.
Jubeir claimed the Tehran attack was similar to what he called earlier Iranian assaults on foreign embassies there, accusing Iran of creating “terrorist cells’ inside Saudi Arabia.
“The kingdom, in light of these realities, announces the cutting of diplomatic relations with Iran and requests the departure of delegates of diplomatic missions of the embassy and consulate and offices related to it within 48 hours. The ambassador has been summoned to notify them,” the foreign minister said.
The Saudi diplomats who were evacuated from Tehran following Saturday night’s attack have arrived in Dubai en route to Saudi Arabia, Al Arabiya reported.
The move comes after angry Iranian protesters stormed and set ablaze the Saudi embassy in Tehran on Saturday night during a rally in condemnation of Riyadh’s execution of prominent Shia cleric Sheikh Nimr al-Nimr.
Nimr was among 47 people beheaded or shot by firing squad across Saudi Arabia on Saturday in the biggest single-day execution spree since 1980.
All but four of the condemned were convicted as Al-Qaeda members, while Nimr and three other Shias were accused of inciting riots among Saudi Arabia’s Shia minority between 2010 and 2012, when Nimr was arrested.
