The current US diplomatic mission put up a large ticker on the east side of its building from which it is beaming subversive messages.
The Cuban leader warned the Bush administration is trying to break diplomatic relations with Cuba, which are at their lowest level, and asserted that "Cuba has nothing to lose."
"They are taking all the steps to bring about a rupture. We are denouncing this to the world, so Cuba is not the one to be blamed for it," he said.
