Egypt's foreign minister says Iran's President Mahmoud Ahmadinejad will visit Cairo this week, marking the first visit to Egypt by an Iranian leader in decades.

Even so, Mohammed Kamel Amr described Ahmadinejad's visit as routine, since he will be attending a summit of the Organization of Islamic Conference in Cairo.

Officials in Cairo did not say Monday whether the Iranian leader would meet Egyptian President Mohammed Morsi during his visit. Morsi is from the fundamentalist Muslim Brotherhood.

Iran and Egypt, both regional heavyweights, once had strong ties. Diplomatic relations deteriorated after the 1979 Islamic Revolution in Iran and Egypt's peace treaty with Israel. Relations remained cold until Egypt's 2011 uprising.

Soon after taking office last summer, Morsi made a historic visit to Tehran to attend a summit of nonaligned nations.
