One of the Arab world's most elite educational institutions, the American University in Cairo, has announced plans to move out of the Egyptian capital to a new suburb being built in the desert.

Officials at the university say it's running out of space at its present headquarters.

Cairo is one of the world's most crowded and polluted cities and the government has been working for twenty years to move people out to new high-rise satellite towns. A BBC correspondent in the city says these have not always proved popular, because of a lack of services and traditional social networks.

But the one the university favours already has a golf-course and plans for luxury houses.
