The UN Security Council "condemned in the strongest terms" the attacks against Saudi embassy in Tehran, and its Consulate General in Mashhad city, which resulted in serious damage and intrusions into the diplomatic and consular premises.
The council members expressed "their deep concern at such attacks," and UN called on the Iranian authorities to protect diplomatic and consular property and personnel, Xinhua reported.
Iran should respect fully their international obligations in this regard, said the 15-nation UN body in a statement on Monday.
"The members of the Security Council called on all parties to maintain dialogue and take steps to reduce tensions in the region," the statement said.
On late Saturday, angry Iranian protesters stormed the Saudi diplomatic mission to protest the execution of 47 individuals on terrorism charges, including a Saudi Shia cleric, Nimr al-Nimr, a member of Saudi Shia community.
