Yasser Arafat is in a "reversible coma" but not brain dead, his spokeswoman said Friday amid conflicting reports about the 75-year-old Palestinian leader's condition. "I can assure you that there is no brain death," Leila Shahid, the Palestinian envoy to France, told French RTL radio. "He is in a coma. We don't know the type but it's a reversible coma." "Today we can say that, given his condition and age, he is at a critical point between life and death." She denied "categorically" persistent reports in French and Israeli media that he was brain dead and being kept alive on life support.
