The audience at an African National Congress event reportedly cheered her announcement.

Naledi Pandor, the foreign minister of South Africa, said at an African National Congress event earlier this week that South Africa will arrest citizens who serve in the Israel Defense Forces upon their return to South Africa.

“I’ve already issued a statement alerting those who are South African and who are fighting alongside or in the Israeli Defense Force [sic]; we are ready—when you come home, we will arrest you,” Pandor said to crowd applause, per Israeli media.

South Africa accused Israel of committing genocide in a case it brought before the International Court of Justice, the principal U.N. judicial arm, in The Hague, late last year.

“South Africa has no regrets about becoming the first country to file a lawsuit against Israel at the International Court of Justice (ICJ) to end its ‘deadly and relentless genocidal bombardment’ of Gaza,” an official South African government publication wrote on Wednesday.

“Over 70,000 have been injured while 10,000 are missing under rubble. This brings the number of civilian casualties to about 110,000, amounting to roughly 5% of Gaza’s 2.3 million population. We will not condone genocide,” Paul Mashatile, deputy South African president, told members of Parliament on Tuesday.
