The State Department and Treasury said the trio have committed or pose a significant risk of committing terrorist attacks that threaten Americans or US national interests.
The move adds them to a list of Specially Designated Global Terrorists, freezing any assets they may have in US jurisdictions and barring Americans from any transactions with them.
Authorities in France and Belgium have identified one of the men, Oussama Atar, as an organizer of both the November 2015 attack in Paris and the March 2016 attack in Brussels that together killed 162 people. The Belgian-Moroccan national is believed to have played a major role in setting up the cell that is blamed for the two strikes.
The third man added to the list is Mohammed Al Binali from Bahrain, who has appeared in numerous propaganda videos encouraging fellow Bahrainis, particularly police and soldiers, to join the Islamic State, according to the State Department.
