The article has a very long list of alleged Israeli violations of international law and human rights. Here's a quick summary.
Genocide in Gaza. It is described as a "genocidal campaign" implying systematic targeting of a national, ethnic, or religious group, prohibited under the 1948 Genocide Convention. This is what the ICC is investigating now.
War Crimes:
- Killing of Palestinian civilians, including children and families.
- Killing of journalist Shireen Abu Akleh, a violation of the Geneva Conventions protecting civilians and journalists in conflict zones.
- Destruction of Palestinian homes in the occupied West Bank, possibly constituting collective punishment or unlawful destruction of property under the Fourth Geneva Convention.
- Intentionally starving civilians by blocking humanitarian aid into Gaza, explicitly prohibited under Article 54 of Additional Protocol I to the Geneva Conventions and cited in ICC arrest warrants for Israeli officials.
- Torture of Palestinian detainees by Israeli forces, a violation of the UN Convention Against Torture.
The article also alleges complicity from the US authorities and corporations (YouTube, Google, MailChimp).
