- NEW: 7 administrative detainees will end their hunger strike, group says
- NEW: All will appear before a review panel for possible release
- Crowds celebrate the deal in Gaza, which eases conditions for prisoners
- "I am glad it's over; I am glad nobody died," an Israeli official says
Jerusalem (CNN) -- Palestinian and Israeli officials both touted an agreement Monday aimed at ending a weeks-long hunger strike by Palestinian prisoners, though a handful of those involved may nonetheless keep up their protest unless they are released.
The announcement that Israel acceded to some requests and agreed to ease conditions for some Palestinian prisoners prompted crowds to pour into the streets of Gaza in celebration.
But even with the deal, not all the 2,000 Palestinians prisoners will necessarily now stop their hunger strike.
Seven administrative detainees who started the protest 77 days ago -- well before the vast majority of participants, who began April 17 -- have agreed to end their strike, no matter what the others do, the Palestinian Prisoner Society said.
Each will get a medical evaluation at the hospital and will then be put in front of a judicial review panel. If Israel has no security evidence against them, they will be released.
The agreement with the administrative detainees adds significance to the deal that had been pushed by Palestinian Authority President Mahmoud Abbas, which was cheered by key players on both sides.
"I am glad it's over. I am glad nobody died," said Yigal Palmor, a spokesman for the Israeli Foreign Ministry.

Palestinian prisoner hunger strike 
Palestinian hunger strike, protests grow The deal, brokered by Egypt, mandates that Israel move Palestinian prisoners in solitary confinement into other prison cells. Issa Qaraqe, the Palestinian minister of detainees and ex-detainees, said this will take effect within 72 hours of the deal being signed.
Israel also will allow families from the West Bank and Gaza to visit inmates. The Israeli Security Agency, in a statement listing details of the agreement, said that will apply only to prisoners' immediate families.
Qaraqe added, during a press conference in Ramallah, that the agreement "talks about the humanitarian and social life in the prisons" and vows "to improve ... living conditions and respond to other demands."
To this point, according to an Israeli Security Agency statement, the Israel Prison Service committee "will discuss additional claims by the prisoners regarding the conditions under which they are being held."
A third element of the agreement cited by the Palestinians relates to if and how Israelis can renew the prison terms of Palestinians held on administrative detention. Those terms are generally six months, but Israel can renew them indefinitely.
The detention terms won't be extended if there is "no security information" -- or, in other words, no evidence that a person poses a security threat to Israel -- Qaraqe said, citing the agreement.
A statement issued by the Israeli Security Agency made no mention of such an offer.
The Israeli agency did say that the agreement states that Palestinian "security prisoners held in Israel ... will refrain from all activity that constitutes practical support for terrorism, including recruiting people for terrorist activity, guidance, financing, coordinating among recruits, aiding recruits, etc."
The agreement covers all security prisoners and "will also be binding on future prisoners," the Israeli statement said.
Palestinian officials did not immediately confirm this part of the agreement.
More than 4,500 Palestinian prisoners are in Israeli prisons for a variety of offenses, ranging from rock-throwing to murder. Of these, about 300 are in administrative detention, according to rights groups.
Abbas has discussed the prisoners' issues with Israeli officials and world leaders, including members of the Middle East Quartet -- the United Nations, the United States, the European Union and Russia.
David Baker, a spokesman for Israeli Prime Minister Benjamin Netanyahu, acknowledged Israel agreed to the deal at Abbas' request.
"It is our hope that this decision will serve to build confidence between the parties and further peace," Baker said.
The details of the deal with Israeli prison authorities ended up being reached in a meeting at Ashkelon prison, the head of the Palestinian Prisoner Association Club, Qadoura Fares, said in a statement
Hanan Ashrawi, a veteran Palestinian lawmaker, called the deal a victory for all Palestinians, including those "in exile."
"The hunger strikers' courage is magnificently inspiring, and their selflessness deeply humbling," Ashrawi said. "They have truly demonstrated that nonviolent resistance is an essential tool in our struggle for freedom."
Qaraqe, the Palestinian detainees minister, similarly celebrated the agreement and expressed thanks to Abbas, Palestinian Prime Minister Salam Fayyad, "the Palestinian people" and especially the protesting prisoners themselves.
He said he offered "a great salute to all our prisoners who have conducted this battle with great pride, to face this unjust oppressor and (to fight) for the dignity and pride of human rights."
