Hamas is about to sign a “comprehensive” agreement with Israel for the lifting of an eight-year blockade placed on the Gaza Strip in return for a long-term ceasefire, a senior Turkish official said on Sunday.

But the agreement is facing domestic opposition from without, as Palestinian factions consider it a potential danger to the political unity of Gaza and the West Bank as stipulated by the Oslo Accords.

In an interview with Hamas daily al-Resalah, Yasin Aktay, an adviser to Turkish Prime Minister Ahmet Davutoglu and deputy chairman of the ruling Justice and Development Party, said that Hamas’s political leader Khaled Mashaal came to Ankara last week to update the Turkish leadership on the details of an agreement reached with Israel and mediated by former British prime minister Tony Blair.

Details of the imminent agreement, reported first by London-based daily al-Hayat on Thursday, have begun to emerge on Hamas news outlets as well over the weekend. According to the reports, Gaza will be allowed to import merchandise through a “floating port” located 3 kilometers (1.8 miles) off the coast. An intermediary port will be established in Cyprus, where all Gaza-bound merchandise will be scrutinized by NATO representatives.

According to Hamas daily al-Resalah, Israel would like to see a larger package deal that would include the exchange of “live and dead Israeli prisoners” held by Hamas — likely a reference to Ethiopian-Israeli citizen Avraham Abere Mengistu and a Bedouin man who both entered the Gaza Strip voluntarily, as well as the remains of Israeli soldiers killed during Operation Protective Edge last summer — in return for Hamas prisoners jailed by Israel.

Israeli Arabic-language website al-Masdar reported on Sunday that Hamas’s leadership held a meeting in Gaza on Friday, specifying the deal’s details. According to al-Masdar’s unnamed Hamas source, Israel has also agreed to allow in thousands of Gazan day laborers through the Erez crossing in return for Hamas’s agreement to stop launching rockets into Israel and digging subterranean attack tunnels underneath the border for a period of at least eight years.

Officials in Israel would not comment on the reported agreement with Hamas.

Hamas’s Shura Council, the movement’s highest deliberative body, endorsed the agreement following a three-hour debate. According to al-Masdar, former Hamas prime minister Ismail Haniyeh expressed concern that the agreement may harm the newly improved relations with Egypt.

“This agreement is no longer just rumors or blabber, but will be signed any minute,” said Walid Awadh, a member of the political office of the Palestinian People’s Party (PPP), formerly the Communist Party, in Gaza. Officials of PLO factions, such as PPP, have been receiving updates from Hamas on the talks with Blair over the past month, he told The Times of Israel.

Awadh said that his party, like all other PLO factions, is opposed in principle to the deal reached between Hamas and Israel. The agreement, carried out unilaterally by Hamas without consulting the PA, strengthens the political divide with Fatah and will eventually detach Gaza completely from the West Bank and Jerusalem, he argued.

“Gaza faces an unknown future,” he said. “This agreement leads us from political divide to [Gaza’s] secession, making it impossible for Gaza to be part of the future Palestinian state.”

Awadh said the agreement is being finalized “far from the Gaza Strip” by Hamas’s overseas leadership in coordination with Qatar and Turkey. Notifying the PLO organizations in Gaza was only done in order to market the agreement and portray it as a result of local consensus. Most factions in Gaza support a ceasefire with Israel, Awadh stressed, but insist that it be the result of “unified Palestinian representation, tying the future of Gaza to that of the West Bank.”

“None of us had the right to debate this agreement or amend it,” he said.

Awadh’s dismay with Hamas was expressed even more bluntly by Fatah spokesman Osama Qawasmi over the weekend.

“Why insist on a naval passageway to the entire world but the West Bank?” Qawasmi wondered in a press statement published on Fatah’s official website. “Why has the land corridor with the West Bank, known as the ‘safe passage,’ not been proposed before anything else, given that the PLO delegation raised the issue forcefully? Is Gaza a humanitarian issue [only] or is it part of the Palestinian homeland?”
