Indirect talks between Israel and Hamas in Cairo to broker an end to the Gaza conflict have so far made no progress, a senior Israeli official said Tuesday.

“The gaps are still very wide, there has not been progress in the negotiations,” he told AFP.

His remarks came as the Egyptian-mediated talks entered their second day and a 72-hour truce held on the ground, bringing relief to millions on both sides of the Gaza border.

The negotiations are aimed at brokering a long-term ceasefire agreement to end a confrontation which erupted on July 8. According to Hamas-run Health Ministry figures, 1,939 Palestinians have been killed in the conflict. The UN says just under three-quarters of those killed in Gaza were civilians and around a third of the civilian victims were children. Israel says 750-1,000 of the dead are Hamas members and other gunmen. It also blames Hamas for all civilian fatalities, saying Hamas sets up rocket launchers and tunnel openings in Gaza neighborhoods and uses Gazans as “human shields.”

Israeli Prime Minister Benjamin Netanyahu had been due to discuss the Cairo talks with his security cabinet later on Tuesday afternoon but the meeting was cancelled, media reports said.

Late on Monday, a Palestinian official in Cairo told AFP that the first day of talks had lasted nearly 10 hours.

“The negotiations were serious,” he said, adding that the Israelis were insisting on the demilitarization of Hamas, the defacto power in Gaza, but that the Palestinians had refused it.

“[Tuesday’s] meeting should be the most important,” he said, indicating the talks were expected to tackle core issues such as the eight-year-old Israeli-Egyptian blockade of the territory, designed to prevent Hamas importing more weapons for its war machine.

Few details have emerged from the negotiations where a Palestinian delegation, comprising senior officials from the Palestine Liberation Organisation, Hamas and Islamic Jihad, is pushing for a removal of the blockade.

For its part, Israel is demanding a full demilitarization of Gaza, with Egyptian negotiators facing an uphill battle to reconcile the two opposing positions.

Netanyahu has said it was “important” that the Ramallah-based Palestinian Authority headed by president Mahmoud Abbas play a role in Gaza’s future, particularly in its reconstruction.
