TEHERAN, Iran — A radical cleric called Saturday for the creation of a “Greater Iran” that would rule over the entire Middle East and Central Asia, in an event that he said would herald the coming of Islam’s expected messiah.

Ayatollah Mohammad Bagher Kharrazi said the creation of what he termed an Islamic United States is a central aim of the political party he leads – called Hizbullah, or Party of God. He added that he hoped to make his vision a reality if the party won the next presidential election.
