Preliminary hearings open on Monday at the UN’s top court in a case that seeks an end to German military and other aid to Israel, based on claims that Berlin is “facilitating” acts of genocide and breaches of international law in Israel’s war in Gaza.

Nicaragua has asked the court to hand down preliminary orders known as provisional measures, including that Germany “immediately suspend its aid to Israel, in particular its military assistance including military equipment in so far as this aid may be used in the violation of the Genocide Convention” and international law, the Guardian reported. 

“We are calm and we will set out our legal position in court,” German foreign ministry spokesperson Sebastian Fischer said ahead of the hearings.

“We reject Nicaragua’s accusations,” Fischer told reporters in Berlin on Friday.

The International Court of Justice (ICJ) will probably take weeks to deliver its preliminary decision and Nicaragua’s case will probably drag on for years.

In January, the ICJ imposed provisional measures ordering Israel to do all it.
