Iran has officially reopened consulate in the Saudi port city of Jeddah following months of talks and an agreement for resumption of diplomatic relations with the Arab kingdom.

The Iranian diplomatic facility in Jeddah, which was closed in 2016, was reopened during a ceremony held in the western Saudi city on Wednesday.

The ceremony, which was attended by a number of Iranian and Saudi officials, saw the Iranian flag being hoisted above the facility as the Iranian national anthem was being played.

A separate ceremony, which was likewise held in Jeddah, where the Organization of Islamic Cooperation (OIC) is headquartered, featured the reopening of the Islamic Republic's Permanent Representative Office at the intergovernmental organization.

A day earlier, Iran had reopened its Embassy in the kingdom's capital of Riyadh during a similar flag-raising ceremony, held with many Iranian and Saudi officials in attendance.

The countries had severed their ties in January 2016 after the execution of Sheikh Nimr al-Nimr, a prominent Shia cleric in Saudi Arabia, prompted angry protests in front of the Saudi Embassy in Tehran and the kingdom's Consulate in the holy city of Mashhad.

Back in March, China successfully mediated high-stakes talks between Tehran and Riyadh, which led to the conclusion of a deal between the two sides that foresaw the resumption of their ties.
