DEIRAL-BALAH, Gaza Strip-An overnight Israeli strike on a school-turned-shelter in Gaza City killed 23 people as Arab mediators worked on a proposal to end the war with Hamas that would include a five-to-seven-year truce and the release of all remaining hostages, officials said Wednesday.

There was no immediate Israeli comment on the strike, which set several tents ablaze, burning people alive. The military said it only targets militants and blames civilian deaths on Hamas because its fighters are embedded in densely populated areas. Another six people were killed in separate strikes, including 5-year-old twin girls.

France, Germany and Britain meanwhile said Israel's seven-week blockade on all imports to Gaza, including food, was "intolerable," in unusually strong criticism from three of the country's closest allies.

Palestinian President Mahmoud Abbas called on Hamas to release the hostages in order to "block Israel's pretexts" for continuing the war. He reiterated his demands that Hamas give up their arms, referring to them as "sons of dogs" in unusually strong language during a speech in the West Bank.

Abbas, who heads the Western-backed Palestinian Authority, has no influence over Hamas but seeks a role in postwar Gaza. Basem Naim, a senior Hamas official, said anyone making such insults has "lost their physical, psychological and mental eligibility for these leadership positions."

Egypt and Qatar still are developing the proposal, which would include the gradual withdrawal of Israeli forces from Gaza and the release of Palestinian prisoners, according to an Egyptian official and a Hamas official who spoke on condition of anonymity because they were not authorized to brief media.

Israel ended a ceasefire with Hamas last month and has vowed to continue the war until all the hostages are returned and Hamas is destroyed or disarmed and sent into exile. It said it will hold parts of Gaza indefinitely and implement President Donald Trump's proposal for the resettlement of the population in other countries, which has been widely rejected internationally.

Hamas has said it will only release the dozens of hostages it holds in return for Palestinian prisoners, a complete Israeli withdrawal and a lasting ceasefire as called for in the now­ defunct agreement reached in January. A Hamas delegation arrived in Cairo late Tuesday to discuss the evolving proposal.

The Egyptian official said the proposed truce, with international guarantees, would last between five and seven years, and that a committee of politically independent technocrats would govern Gaza - a measure Hamas has accepted.

The Hamas official said the militant group is open to a long-term truce that includes the complete withdrawal of Israeli forces and international guarantees, naming Russia, China, Turkey or the United Nations Security Council as possible guarantors.

There was no immediate comment from Israeli officials. Israel has ruled out any arrangement that would allow Hamas to preserve its influence in Gaza and rearm.

The Trump administration, which also has been involved in the ceasefire talks, has said it fully supports Israel's position.

Israel and the U.S. have pressed Hamas to accept a temporary truce in which it would immediately release several hostages in return for vague promises of talks on a more permanent ceasefire. Hamas has rejected those proposals and says it won't disarm as long as Israel occupies Palestinian territory.

The Hamas official said the group does not trust Netanyahu or the U.S. after they shattered the existing ceasefire agreement.
