Ousted President Manuel Zelaya has vowed to return to Honduras on Sunday, despite being threatened with arrest, BBC reported.
In a speech on the regional TV channel, Telesur, Mr Zelaya said he would arrive along with several other presidents.
Mr Zelaya, who was forced out by the military on Sunday, criticised the leaders of the interim government and described them as traitors.
The Organization of American States is holding an extraordinary session and is expected to vote to suspend Honduras.
