Donald Trump has sanctioned the International Criminal Court (ICC), accusing it of "illegitimate and baseless actions targeting America and our close ally Israel".
In his latest round of executive orders, the new US president has taken aim at the ICC and rallied against what he called anti-Christian bias in the US.
It comes as a US federal judge temporarily blocked Mr Trump's plan to reduce the number of government employees.

The ICC order includes financial and travel sanctions against the organisation and its officials, and family members, who are found to have assisted in investigations into US citizens and allies, Sky News' US partner NBC News reported.
The move coincides with a visit to Washington by Israeli Prime Minister Benjamin Netanyahu who, along with his former defence minister Yoav Gallant, is wanted by the ICC over the war in Gaza.
The executive order says that by issuing those warrants, the ICC "further abused its power".
