US President Donald Trump says the first meeting of his newly created Board of Peace will take place on Thursday.

Israeli forces have killed at least 11 Palestinians in attacks across the Gaza Strip, medical sources said, as United States President Donald Trump announced that his newly formed Board of Peace has pledged $5bn to rebuild the war-devastated territory.

The Israeli killings on Sunday mark the latest violation of a US-brokered “ceasefire” that came into effect on October 10.

Hospital sources told Al Jazeera that Israeli forces targeted tents sheltering displaced Palestinians in the Jabalia refugee camp in northern Gaza, killing at least five people.

They said Israeli attacks also killed five others in southern Khan Younis.

Separately, sources in Gaza told Al Jazeera that Israeli forces killed Palestinian Islamic Jihad (PIJ) commander Sami al-Dahdouh in an attack in the Tal al-Hawa neighbourhood, east of Gaza City, on Sunday.

Hazem Qassem, a spokesperson for Hamas, condemned the latest Israeli attacks as a “new massacre” and a “criminal escalation”.

He said they were a “clear attempt to impose a bloody reality on the ground and send a message that all efforts and bodies concerned with establishing calm in Gaza are meaningless, and that the occupation is continuing its aggression despite all parties speaking of the necessity of adhering to the ceasefire agreement”.

According to authorities in Gaza, Israel has killed at least 601 Palestinians and wounded 1,607 others since the “ceasefire” came into effect. The Government Media Office in Gaza also said Israel has carried out at least 1,620 violations of the agreement between October 10, 2025 and February 10, 2026.

Israel accuses Hamas of violating the agreement. It says four soldiers have been killed.

Board of Peace

The latest attacks come as Trump announced that the first meeting of his newly created Board of Peace will take place on Thursday in Washington, DC.

Trump wrote in a post on his Truth Social platform that the members have pledged more than $5bn towards rebuilding war-shattered Gaza, and committed “thousands of personnel to the International Stabilization Force and Local Police to maintain Security and Peace for Gazans”.

The US has asked countries to pay $1bn to join the Board of Peace, suggesting that five countries may have already pledged to do so.

Al Jazeera’s Rosiland Jordan, reporting from Washington, DC, said that “there are reports that the United Arab Emirates has been the first to step forward with this billion-dollar pledge”.

She said that “there are also reports that Kuwait may be coming on board”, leaving three other countries that are not publicly known yet.

Trump did not specify how many of the board’s 20 members would be in attendance at the meeting.

Initially envisaged as a mechanism for ending Israel’s genocidal war on Gaza, Trump’s board has taken shape with his ambition for a much broader mandate of resolving conflicts around the world, in what appears to be a US attempt to bypass the United Nations.

Several key US allies have declined to join the board.

Trump also said in his post that “Hamas must uphold its commitment to Full and Immediate Demilitarization”.

Hamas’s Qassem, meanwhile, called on the Board of Peace to pressure Israel to stop violating the ceasefire and “compel it to implement what was agreed upon without delay or manipulation”.
