The United States has unveiled sanctions on the International Criminal Court, escalating its long-running confrontation with the Hague-based tribunal. The court swiftly condemned the measures as an "assault on the rule of law."

Several ICC member states, including the United Kingdom, said they strongly disagree with the sanctions, setting up a diplomatic rift between Washington and its allies over the court's role and independence.

The ICC, established to prosecute genocide, crimes against humanity and war crimes, has long faced opposition from Washington, which argues the court lacks jurisdiction over American personnel and those of its allies.

The sanctions are expected to complicate the court's operations and test the willingness of member states to stand behind the institution against pressure from the world's most powerful country.
