Israeli President Isaac Herzog has been targeted with a criminal complaint during a visit to Switzerland, Swiss prosecutors said, amid allegations of crimes against humanity over the conflict in Gaza, AFP reports.

The Federal Prosecutor’s Office (BA) confirmed that it had received a criminal complaint against the Israeli president, who was at the World EconomicForum’s annual meeting in Davos on Thursday to discuss the Gaza conflict.

“The criminal complaints will now be examined in accordance with the usual procedure,” BA said in a statement, adding that it was in contact with the foreign ministry “to examine the question of the immunity of the person concerned”.

It did not say what the specific complaints were, or who had filed them.

But a statement allegedly issued by the people behind the complaint, entitled “Legal Action Against Crimes Against Humanity” and obtained by AFP, said several unnamed individuals had filed charges with federal prosecutors and with cantonal authorities in Basel, Bern and Zurich.

The statement said the plaintiffs were seeking a criminal prosecution in parallel to a case brought before the UN’s International Court of Justice by South Africa, which accuses Israel of genocide in its offensive in Gaza.
