Saudi Arabia's ambassador to Iran arrived Tuesday in the Islamic Republic, and his counterpart landed in Riyadh, cementing a restoration of ties between the Gulf rivals after a seven-year rupture in ties.
Riyadh and Tehran severed ties in 2016 after Saudi diplomatic missions in Iran were attacked during protests over Riyadh's execution of Shiite cleric Nimr al-Nimr.
Saudi Arabia's leadership recognises the "importance of strengthening ties, increasing engagement... and taking the (relationship) to broader horizons," ambassador Abdullah Alanazi said upon his arrival in Tehran to take up his duties, according to a Saudi Foreign Ministry statement.
Also on Tuesday, Iran's ambassador to Saudi Arabia, Alireza Enayati, arrived in the capital Riyadh where he was received by foreign ministry officials and embassy staff, according to Iran's official IRNA news agency.
Alanazi was formerly Saudi Arabia's ambassador to Oman, while Enyati was previously Iran's Kuwait envoy.
Saudi Arabia's embassy in Tehran resumed operations last month. In June, Iran marked the reopening of its embassy in Riyadh with a flag-raising ceremony.
Iran and Saudi Arabia have backed opposing sides in conflict zones across the Middle East for years.
