President Mohamed Mursi, the Muslim Brotherhood politician elected in June, kissed Ahmadinejad as he disembarked from his plane at Cairo airport. The leaders walked down a red carpet, Ahmadinejad smiling as he shook hands with waiting dignitaries.

Visiting Cairo to attend an Islamic summit that begins on Wednesday, the president of the Shi'ite Islamist republic is due to meet later on Tuesday with the grand sheikh of al-Azhar, one of the oldest seats of learning in the Sunni world.

"The political geography of the region will change if Iran and Egypt take a unified position on the Palestinian question," Ahmadinejad said in an interview with Al Mayadeen, a Beirut-based TV station, on the eve of his visit.

He said he wanted to visit the Gaza Strip, the Palestinian territory which neighbors Egypt to the east and is run by the Islamist movement Hamas. "If they allow it, I would go to Gaza to visit the people," Ahmadinejad said.
