"We demand to abandon the Witkoff framework and return to the Trump framework – all together or unleash hell on Hamas," the Tikva Forum said in a statement.

Israel has introduced what it said was a new U.S. ceasefire plan and is trying to force Hamas to accept it by imposing a siege on the Gaza Strip.

Israel said Sunday it has stopped the entry of all humanitarian aid into Gaza after phase one of its ceasefire deal with Hamas expired, citing the militant group’s refusal of a US-backed extension.
