But US Secretary of State Mike Pompeo said the ruling was “reckless” and vowed to protect Americans from it.
“This is a truly breathtaking action by an unaccountable, political institution masquerading as a legal body”, he said.
“All the more reckless for this ruling to come just days after the United States signed a historic peace deal on Afghanistan, which is the best chance for peace in a generation.”
The deal was signed with the Taliban last Saturday after more than 18 years of conflict.
The US is not a signatory of the ICC and does not recognise its authority over American citizens.
