Top officials and dignitaries from across the globe have arrived in the Iranian capital Tehran to attend the inauguration ceremony of President Masoud Pezeshkian set to be held on Tuesday afternoon.

The Iranian parliament’s ICANA news agency reported on Monday that officials from Cuba, Columbia, Mongolia, Malta, Niger, Libya, Gambia, Sudan, Myanmar, Ecuador, the Dominican Republic, and Madagascar have so far arrived in Tehran.

They are expected to attend a ceremony at the parliament, during which Pezeshkian, a 69-year-old heart surgeon, will officially swear in as Iran’s new president.

Pezeshkian will take the oath of office before Iranian lawmakers, as well as the Judiciary chief, and members of the Constitutional Council.

More than 70 foreign delegates will be present at the event, which will be broadcast live on state television and covered by over 600 reporters, photographers and cameramen from domestic and foreign media outlets.

Pezeshkian, Iran’s ninth president since the 1979 Islamic Revolution, formally began his four-year mandate on Sunday when Leader of the Islamic Revolution Ayatollah Seyyed Ali Khamenei endorsed his victory in the second round of the presidential vote on July 5. 

Pezeshkian garnered more than 16 million votes against ex-nuclear negotiator Saeed Jalili, who secured upwards of 13 million out of over 30 million votes cast, with the voter turnout standing at almost 50 percent.

The election was called early after Iran’s President Ebrahim Raeisi lost his life in a helicopter crash in May.
