Israel has challenged the impartiality of an International Criminal Court judge appointed to a panel deciding whether an arrest warrant should be issued for Israeli Prime Minister Benjamin Netanyahu. The move could further delay a decision in the case, in which the ICC chief prosecutor filed a request for arrest warrants against Netanyahu and three Hamas leaders over the Gaza war. Israel has questioned the judge's previous employment with the Office of the Prosecutor and has requested information to clarify her impartiality. The court has no set deadlines but has generally taken about three months to rule on requests for arrest warrants in previous cases.
