High-ranking dignitaries from different countries have arrived in the Iranian capital Tehran to participate in President Masoud Pezeshkian’s inauguration ceremony.

According to The Iran Project, 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 on Tuesday afternoon, 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. 

During the endorsement ceremony, Pezeshkian vowed to follow “the path of fairness and justice,” serve the people and address their problems, adding that these tasks would be “impossible without sticking to the law and unity.”

In a speech, Ayatollah Khamenei praised Pezeshkian as a “competent president,” saying, “We all have to help him and his government do great jobs.”

In a decree, giving his official approval for Pezeshkian, the Leader said the new Iranian president was a “wise, honest, popular, and scholarly” person.
