In an update on the legal / ICJ front:
The government of Nicaragua appears to have put the governments of the United Kingdom, Germany, the Netherlands, and Canada on notice over what it regards as complicity and hence potential violations of the genocide convention.

Some quotes from the article (translated):
The Government of Reconciliation and National Unity informs the People of Nicaragua and the International Community that it has notified the governments of the United Kingdom, Germany, the Netherlands and Canada of its decision to hold them responsible under International Law for flagrant and systematic violations of the Convention for the Prevention and Punishment of the Crime of Genocide, International Humanitarian Law and Customary Law, including the Law on occupation in the Occupied Palestinian Territories, in particular the Gaza Strip.
[...]
The obligation to prevent genocide arises and begins when there is a risk of its occurrence; in fact, when it is plausible that it is occurring or may occur. This probability is now beyond all doubt and controversy.
In this sense, Nicaragua has urged the Governments of the United Kingdom, Germany, the Netherlands and Canada to immediately stop the supply of weapons, ammunition, technology and/or components to Israel, since it is plausible that they have been used to facilitate or commit violations of the Genocide Convention, including, but not limited to, acts of genocide, attempted genocide, complicity in genocide, and conspiracy to commit genocide.

Furthermore, Nicaragua has warned that recent announcements by these governments regarding the suspension of funds to the United Nations Relief and Works Agency for Palestine Refugees in the Near East (UNRWA) further demonstrate that in the current scenario, the Governments of the United Kingdom, Germany, the Netherlands and Canada continue to ignore their obligations and actively facilitate violations of the norms of International Law by Israel to the serious and immediate detriment of the Palestinian People, in particular the inhabitants of Gaza, and the International Community as a whole. In particular, Nicaragua has stressed that this act contributes to the collective punishment of the Palestinians and the apparent objective of forcing the Palestinian population to abandon the Occupied Palestinian Territories, particularly Gaza, and prevent the exercise of their Right to Self-Determination.
