Cuba mourns revolutionary leader Castro

Cuba mourned revolutionary leader Fidel Castro on Sunday as the communist island prepared to say its last goodbyes to the towering giant of its modern history with mass memorials and a four-day funeral procession. Castro, whose iron-fisted rule defied the United States for half a century, died late Friday after surviving 11 US administrations and hundreds of assassination attempts. A series of memorials will begin Monday, when Cubans are called to converge on Havana's iconic Revolution Square.
