Once again, relations between the two countries collapsed with the sudden eruption of the Iranian Revolution in Iran in 1978–79. When the Shah fell, Egypt was bound to disapprove of his replacement, Ruhollah Khomeini, who returned the sentiment in full measure. Furthermore, in 1979, Anwar Sadat infuriated the new Iranian government by welcoming Mohammad Reza Pahlavi, the exiled Shah of Iran, for a short, but indefinite, stay. In 1979, Iran officially cut all ties with Egypt. This move was a response to the 1978 Camp David Accords, as well as Egypt's support for Iraq in the Iran–Iraq War. In 1981, Iran symbolically dedicated a street to Khaled Islambouli, Sadat's assassin.
