Visiting the city to express condolences and hold counterterrorism talks with European authorities, Kerry did not give details on the Americans' deaths, but a senior official said their families have been informed.
The AP reports that at least six people have been detained after raids related to Tuesday's attacks, which also injured more than 270, and that Belgian lawmakers are discussing ways to increase security measures.
Reports have indicated that the same Belgium-based ISIS cell responsible for this week's strike was behind November's coordinated assaults in Paris that left more than 130 dead. Belgium's top interior and justice officials offered to resign this week amid indications that signs of a looming attack were missed, but Michel refused their resignations.
"The United States stands firmly with Belgium and with the nations of Europe in the face of this tragedy,” Kerry said Friday.
