WATCH: White House holds briefing as Israeli officials worry ICC will issue arrest warrants

White House press secretary Karine Jean-Pierre will hold a news briefing on Monday as U.S. ally Israel appears to be increasingly concerned that the International Criminal Court may issue arrest warrants against the country’s leaders.

The ICC launched a probe three years ago into possible war crimes committed by Israel and Palestinian militants going back to the 2014 Israel-Hamas war, but it has given no indication such warrants are imminent. There was no comment from the court on Monday.

Israel’s Foreign Ministry said late Sunday that it had informed Israeli missions of “rumors” that warrants might be issued against senior political and military officials.

Foreign Minister Israel Katz said “we expect the court to prevent the issuance of arrest warrants against senior Israeli officials,” saying such warrants would “provide a morale boost” to Hamas and other groups that Israel is fighting.

A series of Israeli announcements in recent days about allowing more humanitarian aid into Gaza appears to be aimed in part at heading off possible ICC action.

Neither Israel nor its close ally the United States accept the ICC’s jurisdiction, but any warrants could put Israeli officials at risk of arrest in other countries. They would also serve as a major rebuke of Israel’s actions toward the Palestinians.

The International Court of Justice, a separate body, is investigating whether Israel has committed acts of genocide in the ongoing war in Gaza, with any ruling expected to take years. Israel has rejected allegations of wrongdoing and accused both international courts of bias.
