The United Nations' highest court on Wednesday ordered the United States to lift sanctions on Iran that affect imports of humanitarian goods and products and services linked to civil aviation safety.

The ruling by the International Court of Justice is legally binding, but it remains to be seen if the administration of President Donald Trump will comply.

Trump moved to restore tough U.S. sanctions in May after withdrawing from Tehran's nuclear accord with world powers. Iran challenged the sanctions in a case filed in July at the International Court of Justice.

In a preliminary ruling, the court said that Washington must "remove, by means of its choosing, any impediments arising from" the re-imposition of sanctions to the export to Iran of medicine and medical devices, food and agricultural commodities and spare parts and equipment necessary to ensure the safety of civil aviation.

By limiting the order to sanctions covering humanitarian goods and the civil aviation industry, the ruling did not go as far as Iran had requested.

The U.S. ambassador to the Netherlands, Peter Hoekstra, pointed that out in a tweet.

"This is a meritless case over which the court has no jurisdiction," the ambassador tweeted. "Even so, it is worth noting that the Court declined today to grant the sweeping measures requested by Iran. Instead, the Court issued a narrow decision on a very limited range of sectors."

While imposing the so-called "provisional measures," the court's president, Abdulqawi Ahmed Yusuf, stressed that the case will continue and the United States could still challenge the court's jurisdiction.
