Cairo truce talks: key Israeli and Palestinian demands

Here are their key demands and seemingly irreconcilable positions:

Hamas and the Palestinian Authority want Israel to end a land and sea blockade imposed on Gaza in 2006 after Hamas captured Israeli soldier Gilad Shalit.

Israel tightened the blockade in summer 2007 after Hamas forcibly took over Gaza, ousting forces loyal to president Mahmud Abbas.

Israel eased restrictions on imports of food and construction materials in 2010 following international outcry over a botched Israeli raid on a Gaza-bound flotilla which was trying break the blockade, which left 10 Turks dead.

Some restrictions were further eased after the last Israel-Hamas conflict in Gaza in 2012.

Hamas wants fishing zones extended, and to have a port and an airport.

The Palestinians want Egypt to reopen the Rafah border crossing, where Israel has no jurisdiction.

Gaza residents have only two ways to access the outside world: through the Rafah crossing with Egypt or through the northern Erez crossing into Israel. There is also a goods terminal at Kerem Shalom, at the southernmost point of the Israel-Gaza border.

There are four other crossing points into Gaza which have been closed for years: Sufa in the south, Kissufim in central Gaza and Karni and Nahal Oz in the north. The Palestinians want all of them reopened.

Egypt has kept Rafah closed since the July 2013 army overthrow of Islamist president Mohamed Morsi, whose Muslim Brotherhood movement was a close ally of Hamas.

Relations between Egypt and Hamas have collapsed since Morsi's demise. The new regime in Egypt, one of only two Arab countries that have a peace treaty with Israel, says it has destroyed more than 1,600 cross-border smuggling tunnels leading from Gaza into the Sinai Peninsula.

Israel says it is ready to ease the blockade only if its security needs are guaranteed.

Prime Minister Benjamin Netanyahu has demanded the de-militarisation of the Gaza Strip and conditioned support for reconstruction on the disarmament of Hamas and other militant groups.

Hamas has flatly refused.

Netanyahu wants strict controls on goods crossing into Gaza and international oversight on materials imported for reconstruction to ensure that Hamas cannot rebuild a complex network of cross-border tunnels used for infiltrating the Israeli south.

Hamas wants Israel to free around 60 prisoners, who were released in a prisoner swap deal in 2011 then re-arrested in June after three Israeli teenagers were kidnapped and murdered in the West Bank.

They are also asking for the release of 37 Palestinian MPs who have been arrested by Israel over the years, all but two of them Hamas members.

They are also asking for the release of scores of Palestinian MPs who have been arrested by Israel over the years.

Israel has refuses to release them.

Hamas and the Palestine Liberation Organisation president Mahmoud Abbas are officially negotiating as one in Cairo. In April, Hamas signed a unity agreement with the PLO, which is dominated by Fatah and which has been at odds with Hamas for years. The reconciliation saw the former rivals setting up a consensus government that took office in June, ending seven years of separate administrations.

Israel wants Abbas's security forces to retake control of Gaza and deploy on the Palestinian side of the Egyptian border crossing and for international donor money to be dispersed through Abbas.
