The U.S. government on Monday called on followers and oppositions of ousted Honduran President Manuel Zelaya to "abstain from any provocative actions."
"We continue to believe that the best mechanism to restore the democratic order (in Honduras) is through the San Jose Agreement," the U.S. embassy in Tegucigalpa said in a short statement.
Costa Rican President Oscar Arias proposed the San Jose Agreement, which includes Zelaya's restoration into power, political amnesty, and to advance the general elections from November to October.
Zelaya announced his surprising return to Honduras on Monday and is currently being hosted at the Brazilian embassy in Tegucigalpa, where thousands of his followers gathered to show their support.
Meanwhile, the de facto Honduran government on Monday restored the curfew in the country which will be valid from at 16:00 (2200 GMT) to 7:00 a.m. (1300 GMT).
"We request your patience, comprehension and collaboration with these measures taken to protect the peace, life and property of the people," said a spokesman from the de facto government.
In a press conference on Monday, Zelaya said he returned to Honduras to solve the crisis and seek peace for the country.
Zelaya was ousted on June 28 and taken by force to Costa Rica, since then the de facto government established a curfew from 21:00 (0300 GMT) to 6:00 a.m. (1200 GMT). The curfew had later been reduced and suspended.
