Secretary of State Hillary Rodham Clinton says the action taken against Honduras' president should be condemned by everyone.
She says Honduras must embrace the principles of democracy and respect constitutional order.
The president, Manuel Zelaya, was flown to Costa Rica after being taken into military custody at his house outside the Honduran capital.
He was detained shortly before voting was to begin on a constitutional referendum the president had insisted on holding. The Supreme Court had ruled it illegal and everyone from the military to Congress and members of his own party opposed it.
