The Turkish government will be allowed to sponsor major infrastructure projects in Gaza as part of its new agreement with Israel.

While senior officials in Jerusalem hope that this will help prolong the ceasefire between Israel and Hamas, they are also concerned that the projects could become flashpoints between the two countries in the future.

The details of the rapprochement were revealed this week when families of missing Israelis in Gaza won a High Court injunction to force the Israeli government to disclose parts of the deal.

According to the deal, Israel will allow Turkey to transfer building materials and funds to Gaza. All the Turkish goods will go through Israel's Ashdod Port and the funds can only be wired through approved banks. Turkey is also interested in building a new power plant and desalination facility in Gaza.

The first Turkish ship with supplies for Gaza arrived at Ashdod last weekend.

The Israeli government hopes that the investment in Gaza's infrastructure will alleviate the situation in the Strip, where electricity is currently available only eight hours a day and there are water shortages, as well as creating an incentive for the Palestinians to maintain the ceasefire. If these projects are successful, they could lead to more ambitious developments, including a new port and an offshore gas field.

However, while the agreement specifies that the Turkish projects will only take place in "a period of calm", some in the Israeli security establishment are concerned that they may be used at some stage as cover by Hamas operatives, pushing Israel into another crisis with Ankara.

"I don't think we'll be able to trust them as long as a hostile president like [Recep Tayyip] Erdogan is in power," said one Israeli intelligence officer.
