Cuban revolutionary leader Fidel Castro, who built a communist state on the doorstep of the United States, and for five decades defied its efforts to topple him has died at 90, Cuban television is reporting. Castro died on Friday at 7 p.m. Castro and his guerrilla forces were responsible for overthrow of Cuban dictator Fulgencio Batista in 1958.

He ruled the country with an iron fist and his close ties to other Communist nations led to frayed relations with the US. Diplomatic relations between the two countries almost led to a nuclear confrontation during the Cuban missile crisis in 1962. Castro stepped down from office in 2008 and his brother Raul Castro took over.
