A statement issued by Muslim Brotherhood leader Mohammed Mahdi Akef condemned the Israeli military actions.
"I will quote the Israeli defense minister as describing it as a holocaust," it said.
The Lebanese Hezbollah guerrilla group also described the attacks as a holocaust taking place "with blatant Arab complacency and Western weapons and financing and comprehensive American protection of the Israeli butcher."
Syria also condemned the attacks and said the international community should break its silence by "deterring Israel from committing these massacres."
The Arab Gulf states, for their part, denounced the "savage Israeli aggressions" in Gaza and urged the international community to "take its responsibilities and take the necessary measures to protect the Palestinian people."
