Iran's charge d'affaires in Cairo, Mujtaba Amani, and Deputy foreign Minister for Arab and African Affairs, Hossein Amir-Abdollahian will attend inauguration of President-Elect Abdel-Fattah El-Sisi on Sunday, Egypt's state-run news agency reported.

Iranian president Hassan Rouhani received an invitation late on Monday from Egypt's interim leader Adly Mansour to attend the inauguration of Egypt's upcoming president Abdel-Fattah El-Sisi.

The swearing-in ceremony will be attended by at least 45 Arab and International figures, including 15 world leaders, Al-Ahram's Arabic website reported.

The ceremony will be followed by an inauguration gala event at the presidential palace in Heliopolis.Celebrations will also take place in the vicinity of the palace.

El-Sisi, the former minister of defense, won a landslide in the May presidential election, gaining almost 97 percent of the vote.

According to the Tehran-based Fares news agency, the invitation was handed in to the Iranian Chief-of-Staff Mohamed Nahavandian, who expressed his hope "that the democratic process in Egypt will reflect the will of the people".

He further affirmed the importance of historic and cultural ties between Egypt and Iran, stressing the need for communication between them.

Egypt's official ties with Iran were broken off in 1980, a year after Iran's Islamic revolution and Egypt's peace agreement with Israel.

Egypt-Iran relations had begun to thaw following ousted president Mohamed Morsi's rise to power, when Morsi and then-president Mahmoud Ahmadinejad exchanged visits and spoke of a new phase in bilateral relations.
