Fidel Castro leads first mass rally in four years

HAVANA — Cuban revolutionary leader Fidel Castro on Friday led his first mass rally since an illness forced him from the presidency four years ago.

Castro, 84, wearing his trademark olive green uniform -- but without any military insignias -- addressed thousands of students and others at the University of Havana, where he warned about the threat of nuclear war should the United States or Israel attack Iran.

Castro began to reemerge from seclusion about two months ago, after recovering from instestinal surgery that forced him to hand over power to his younger brother Raul Castro in July 2006
