Turkey will submit on Wednesday a declaration of intervention in South Africa's genocide case against Israel at the International Court of Justice (ICJ) in the Hague, a diplomatic source said.
The source added that the declaration will happen at 1330 GMT after Foreign Minister Hakan Fidan said this week that Turkey would make the declaration on Wednesday.
"Turkey's intervention pushes the international community to recognize and address the humanitarian crisis in Gaza," the source said.
In May, Turkey said it had decided to join the case launched by South Africa as it stepped up measures against Israel over the assault on Gaza, adding that its bid would follow the necessary legal preparations.
In June, Spain said it had asked to intervene in the case at the ICJ, the highest legal body of the United Nations, established in 1945 to resolve disputes between states.
Israel has repeatedly dismissed the case's accusations of genocide as baseless, arguing in court that its operations in Gaza are self-defense and targeted at Hamas militants who attacked Israel on October 7.
