The petition was signed by 525 Italians, mainly academics, Haaretz reported. The signees say they are dismayed by the events in Gaza and accuse Israel of pursuing colonial policies and “ethnic cleansing” of the Palestinians.

The document calls for Israel to face an international tribunal, a Nuremberg-like trial, for its war crimes and the “slow genocide” of the Palestinian people. Italian activists believe that not only the Israeli military and the government, but also the entire state of Israel and “its accomplices” should be brought to trial over current events, as well as those in the past and “the foreseeable future.”

The online document also blames the US for supporting Israel, and the EU for “active or passive complicity” in Israel's actions against the Palestinian people.

The petition signees also accuse the United Nations of its failure to stop Israel. The Western media, according to activists, paints the events in the wrong light, justifying the Israeli offensive in Gaza as a self-defense operation.

Called 'Noi Accusiamo' (We Accuse), the petition was initially published on an academic website, Historia Magistra, but has gone viral after being re-posted on the website of left-wing newspaper Il Manifesto.

The publication comes amid growing international criticism over Israel's operation in the Gaza Strip. The four-week offensive has already claimed over 1,800 Palestinian lives – most of whom were civilians, according to rights groups.
