Fidel Castro: Obama brought 'sweetened words'

Cuban revolutionary leader Fidel Castro broke his silence on US President Barack Obama's recent trip to Cuba, saying he brought "sweetened words", but little of substance, a media report said on Monday.

In a kind of open letter to Obama, published on Monday in state-run daily Granma, Castro said he had "the elemental duty to respond to the speech Obama delivered" to the Cuban people during his recent visit on March 20 to 22.

"Obama made a speech in which he used the most sweetened words to express: 'It is time, now, to forget the past, leave the past behind, let us look to the future together, a future of hope'." Castro said.
