Ireland joins genocide case against Israel at International Court of Justice, citing Gaza atrocities

Ireland became the latest country to join South Africa’s genocide case against Israel, the International Court of Justice (ICJ) announced on Tuesday.

The case accuses Israel of committing genocide during its military operations in Gaza. Other nations supporting the case include Nicaragua, Colombia, Mexico, Libya, Bolivia, Turkey, the Maldives, Chile, Spain, and the State of Palestine.

South Africa first filed its case against Israel in December 2023, accusing the country of committing genocide during its ongoing offensive in the Gaza Strip.

Ireland’s declaration, submitted on Monday, does not add new allegations. Instead, it underscores a legal argument that intent can be inferred when the consequences of actions are foreseeably destructive to a group.

The Irish government first announced its intention to intervene in March 2024. This marks a significant escalation in Ireland’s critical stance toward Israel’s conduct in Gaza.

Diplomatic ties between Ireland and Israel have been fraught. In December, Israel closed its embassy in Dublin, with Israel's Foreign Minister Gideon Sa’ar accusing Ireland of “antisemitic rhetoric.” Irish Prime Minister Simon Harris called the closure “deeply regrettable.”

Ireland’s solidarity with Palestine has deep historical roots, tied to its own experience of British colonial rule. Nationalist communities in Northern Ireland often display Palestinian flags as a symbol of shared struggles. Israel’s President Isaac Herzog also has Irish ties, with his grandfather serving as Chief Rabbi of the Irish Free State before moving to Israel.
