The Palestinian Islamic Jihad, which in addition to Hamas holds hostages in Gaza, affirmed it will remain alert to guarantee the full implementation of the ceasefire in Gaza, it said in a statement on Wednesday.

"Hamas is reneging on the understandings and creating a last-minute crisis that is preventing an agreement," the Prime Minister's Office announced on Thursday morning."Hamas is retracting explicit understandings that were agreed upon with the mediators and Israel in a last-minute attempt at extortion.""Israel will not set a date for a Cabinet or government meeting until the mediators announce that Hamas has approved all details of the agreement," the statement concluded.

Three Palestinians were killed and scores more injured by an Israeli air strike in the West Bank city of Jenin on Wednesday, the Palestinian Red Crescent said.The Israeli military said it had conducted a strike in the area of Jenin but did not give further details.The Jenin camp has long been a hotbed of militants with an array of light weapons and a growing arsenal of explosive devices. The Israeli military regularly accuses militant groups of basing fighters within densely populated urban areas such as refugee camps that date back to 1948. Many of the terrorists live in the camp, often with their families.Terror groups have grown in strength in Jenin, where Israel estimates almost half the population is affiliated to Islamic Jihad or Hamas.

The United Nations is committed to delivering humanitarian aid to Palestinians in the Gaza Strip during the ceasefire, but "we can only deliver as much as the conditions on the ground allow for us to do so," a UN aid spokesperson said."The removal of the various impediments the UN has been facing during the last year – which include restrictions on the entry of goods; the lack of safety and security; the breakdown of law and order; and the lack of fuel – is a must," said Eri Kaneko, spokesperson for the UN Office for the Coordination of Humanitarian Affairs.

Prime Minister Benjamin Netanyahu held a conference call with the negotiating team in Doha, who reported on last-minute attempts by Hamas to back out of the hostage agreement, the Prime Minister's Office announced in a statement on Thursday."Contrary to an explicit clause that gives Israel veto power over the release of mass murderers who are symbols of terror, Hamas demands to dictate the identity of these terrorists," the statement said. "The Prime Minister instructed the negotiating team to stand firm on the agreed understandings, and to outright reject Hamas's last-minute extortion attempts."

Palestinian group Hamas is committed to the ceasefire agreement announced by mediators on Wednesday, Senior group official Izzat el-Reshiq said on Thursday.Israeli Prime Minister Benjamin Netanyahu earlier accused Hamas of backtracking on some details of the ceasefire deal.
