Havana  - Traditional Cuban leader Fidel Castro on Monday complained that the weekend Summit of the Americas in Trinidad and Tobago was held in "secret."

But at the same time, amid a dawning - though as yet far from complete - thaw in US-Cuban relations, Castro had some praise for US President Barack Obama.

"His predecessor (George W Bush) went to sleep early and slept many hours. It seems that Obama works a lot and sleeps little," he quipped in an article published on the website Cubadebate.

Havana  - Historic Cuban leader Fidel Castro accused British Prime Minister Gordon Brown of treating peers, including US President Barack Obama, "with prejudice" during the recent Group of 20 summit in London.

Havana/Washington  - After meeting with US lawmakers, Cuba's retired leader Fidel Castro said Wednesday that while he believes US President Barack Obama's intentions towards Cuba are "sincere," they clash with the "objective reality" within the United States.

The man who formally stepped down from power in Cuba in February 2008 after almost half-a-century was reacting to comments made by US Democratic Representative Laura Richardson.

Havana  - Cuba's retired leader Fidel Castro Wednesday showed a flash of his former outspoken self, writing that this week's G20 summit in London reflects deep conflicts and yet holds the welfare of the world's workers in its hands.

Fidel wrote that the changes had been discussed with him in advance.

Caracas, Feb. 28 : Venezuelan President Hugo Chavez has said 82-year-old former Cuban leader Fidel Castro seemed to be in a "very, very good shape" during their latest meeting in Cuba.
