Bolivia has joined South Africa’s case against Israel at the International Court of Justice that alleges the Israeli Gaza offensive breaches the UN Genocide Convention, AFP reports according to the court.

Bolivia already announced in November it was severing diplomatic ties over what it described as the “disproportionate” attacks on Gaza by Israel. At the time, Israel slammed the move as “a surrender to terrorism”.

In its submission to the court made public on Wednesday, Bolivia argued: “Israel’s genocidal war continues, and the Court’s orders remain dead letters to Israel.” While ICJ rulings are legally binding, the court has no concrete means to enforce them.
