Havana ? Cuba’s state-run media said Saturday that an opposition activist who has refused food and water for 129 days has actually gained weight due to intravenous feeding, but that he has suffered a blood clot that left him “in danger of potential death.”

In an unusual step, the Communist Party newspaper Granma reported that Guillermo Farinas is conscious and stable but could slip into grave condition at any time.

Farinas has drawn international attention since he stopped eating and drinking on Feb. 24 to demand that authorities free dozens of political prisoners and to protest the death of Orlando Zapata Tamayo, who died after his own long hunger strike in prison — the first Cuban opposition figure to die after refusing food in nearly 40 years.
