Israel Prisons Service said on Monday that a Palestinian prisoner who has been on hunger strike for more than 80 days, had ended his protest, but Palestinian sources, including his lawyer, denied the claim.
"(Mahmud) Sarsak ended his hunger strike," IPS spokeswomanSivan Weizman told AFP, saying he had taken the decision to end his fast after consulting his lawyer and the prison administration.
But Sarsak's family in Gaza, as well as the Palestinian Prisoners' Club in Ramallah, denied that he had ended his strike.
And his lawyer, Mohammed Jabarin, said he had no comment on the Israeli claim.
Weizman said Sarsak, who is being held in the infirmary wing at Ramle prison, gave no reason for ending his hunger strike, and said his health was being monitored as he gradually started eating again.
Sarsak began refusing food in late March along with several other prisoners in a protest which in April was joined by more than 1,000 detainees demanding better conditions, including increased access to lawyers and visits from relatives in Gaza.
He and others also sought an end to the practice of holding suspects in administrative detention, under which a military court can order an individual held without charge for renewable periods of six months.
The mass hunger strike ended on May 14, with a deal that saw Israel agree to ease prison conditions, but not end administrative detention.
Sarsak continued his hunger strike and his health has been deteriorating, with prison authorities transferring him briefly to a civilian hospital on Sunday night before returning him to the Ramle prison near Tel Aviv.
