The signatories called on Muslim nations — particularly Arab states — to leverage their political and economic influence, including through measures such as severing ties with Israel, imposing oil and gas embargoes and opening border crossings for humanitarian aid. Israel has denied accusations of genocide to characterize its military actions in Gaza following the Oct. 7, 2023 attack by Hamas that killed nearly 1,200 people. Hamas also took hostage more than 250 Israeli civilians and military personnel during the operation. Since then, Israeli airstrikes and attacks have killed at least 61,000 Palestinians, a third of them children, according to Gaza’s Health Ministry. The signers also urged governments to lead diplomatic convoys to Gaza crossings and personally demand Israel allow the unrestricted flow of aid.
