The Trump administration is slapping sanctions on four judges at the International Criminal Court over the tribunal’s investigation into alleged war crimes by Israel in its war against Hamas in Gaza and in the West Bank.

Mahmoud Daifallah Hmoud was appointed following a parallel and independent voting process in the General Assembly and Security Council, conducted by secret ballot.

The U.S. sanctions targeted four judges, two of whom authorized arrest warrants for top Israeli officials, including Prime Minister Benjamin Netanyahu.
