Palestinian negotiators have threatened to leave Cairo Sunday if the Zionist entity failed to show "seriousness" in Egypt-hosted talks aimed at striking a long-term ceasefire in the Gaza Strip.

"Sunday will be a decisive day and this depends on the behavior of the Israeli side," Bassam al-Salehi, a member of a Palestinian negotiating team, told media outlets on Sunday.

Salehi said that the Palestinian side will consult with Egypt on their decision to leave Cairo.

"The Egyptian side knows our keenness on the success of the negotiations and knows that the Israeli side is trying to blackmail us," he said.

The head of the delegation Azzam Ahmed said Saturday "tomorrow we have a meeting with the Egyptian leadership in the morning and on the basis of that we will decide our future plan."

"We will leave Cairo tomorrow if it is confirmed to us that they will not return except with conditions."

Prime Minister Benjamin Netanyahu said on Sunday that the Jewish entity would stay away from Egyptian-mediated truce talks with Hamas as long as Palestinian rocket and mortar attacks from the Gaza Strip continued.

"Israel will not negotiate under fire," Netanyahu said in broadcast remarks at the weekly meeting of his cabinet, in Tel Aviv.

"At no stage did we declare (Israel's military offensive) was over," he said. "The operation will continue until its objective - the restoration of quiet over a protracted period - is achieved. I said at the beginning and throughout the operation - it will take time, and stamina is required."

Palestinians say the Zionist authorities refused to accept demands including an end to the blockade of Gaza and the opening of a seaport.

The balance of power on the ground between the Palestinian resistance and the enemy had changed, a senior leader of the Gaza-based Palestinian resistance movement Hamas said Saturday.

"The resistance will cross the border in the next battle to kill Israel's soldiers," Osama Hamdan, the chief of international relations at the movement, added.

He said during a political gathering in the Moroccan capital Rabat that Hamas has videos showing the enormity of the losses the Zionist army had sustained during its offensive on the Gaza Strip.

Hamdan added that support given the Palestinian resistance by Arab countries contributed to what he called the achievements this resistance made in the past weeks.

Hamdan called on Arab peoples to keep on supporting the Palestinians in their struggle against the Zionist occupation of their territories and violations against the Gaza Strip.
