US President Donald Trump’s administration is preparing to impose sweeping sanctions on the International Criminal Court (ICC), according to officials, a sharp escalation in Washington’s efforts to dismantle the institution after it issued an arrest warrant for Israeli Prime Minister Benjamin Netanyahu, The Wall Street Journal (WSJ) reports.

The sanctions would forbid most transactions with the ICC after a grace period of six to seven months, according to documents viewed by WSJ and US officials. That could potentially cripple the court by prohibiting it from conducting transactions in US dollars, cutting it off from much of the global financial system.

The US officials who spoke to WSJ said that these sanctions could be agreed upon this week during the session of the UN General Assembly.
