Michael Oren, an Israeli parliamentarian and former ambassador to the United States, said that the New York Times had committed a "journalistic terrorist attack" in publishing an op-ed by imprisoned Palestinian leader Marwan Barghouti.
The strike has been called for by prominent Palestinian prisoner and leader Marwan Barghouti, who is now serving a life sentence over his role in the second Palestinian intifada - or uprising.
According to the Israeli Prison Service, 700 Palestinian prisoners have declared that they will join the hunger strike, a number that the service expects to increase in coming days. Some 500 are held under administrative detention, which allows for imprisonment without charges or trial.
Because Barghouti highlights two of Israel's most pernicious lies: that there is no one to talk to on the Palestine side (when in fact it is the Palestinians who are still seeking a partner for peace), and that the resistance to Israel's occupation is violent.
"Having spent the last 15 years in an Israeli prison, I have been both a witness to and a victim of Israel's illegal system of mass arbitrary arrests and ill-treatment of Palestinian prisoners", he wrote.
Palestinian officials said some 1,500 inmates affiliated with all political factions including rival Fatah and Hamas were taking part in the protest.
The Israel Prisons Service spokesman Assaf Librati said Barghouti had been transferred from Hadarim Prison to the Kishon Prison, near Haifa.
Israeli authorities have placed him under solitary confinement for calling the strike - now in its second day. "My policy is that you can't negotiate with prisoners such as these".
Israeli authorities have ruled out negotiating with the striking Palestinian prisoners.
Demonstrators gather during a rally in support of Palestinian prisoners on hunger strike in Israeli jails, in the West Bank city of Ramallah April 17, 2017. Nowhere is there any reference to Barghouti's leadership of the Palestinian terror group Tanzim, or his multiple murder convictions.
In an interview on Monday with the Times's editorial board, Mansour also said he had spoken by telephone with Barghouti's wife and quoted her as saying that "we hope this hunger strike will be short" and that the Israelis would grant the strikers' demands.
"When a despicable murderer like Barghouti protests in prison for improved conditions, while the relatives of those he murdered are still in pain, there is only one solution - death penalty for terrorists", Katz tweeted Monday.
Opinion polls indicate that Barghouti enjoys widespread support in his quest to replace Palestinian president Mahmoud Abbas.
