A top US diplomat says deposed Honduran President Manuel Zelaya was "irresponsible and foolish" to return before a settlement had been reached.
Lewis Amselem, US ambassador to the Organization of American States (OAS), said Washington had asked Mr Zelaya not to return because of potential unrest.
He called on him to urge his supporters to keep their protests peaceful.
Earlier, Honduran troops raided two media outlets that had been critical of the interim government.
Radio Globo and Cholusat Sur TV were closed after authorities issued a state of emergency suspending key civil liberties for 45 days.
The measures were in response to a call by Mr Zelaya for his supporters to stage a protest exactly three months since he was deposed.
Mr Zelaya is holed up in the Brazilian embassy in the capital Tegucigalpa after his dramatic return last week. read more
