Madrid/Tegucigalpa, Sep 25 (DPA) Honduras' ousted President Manuel Zelaya has said he fears for his life, Spanish media reported Thursday.

In a telephone interview with the Spanish daily El Mundo, Zelaya said the US and the Organisation of American States (OAS) had helped to foil one plan to kill him and to make it look like suicide.

'Today there is still the risk that the embassy will be assaulted and my suicide will be announced,' he said.

The de facto government headed by Roberto Micheletti has denied plans to attack the Brazilian embassy in Tegucigalpa, where Zelaya has taken refuge.

Thousands of supporters of Micheletti and Zelaya took to the streets Thursday in separate demonstrations.

While Micheletti's supporters - dressed in white - demanded the end of 'foreign interference' in Honduras, Zelaya's supporters - wearing red - demanded the reinstatement of the ousted president. Both groups intended to march towards the Brazilian embassy.

Zelaya returned secretly to Honduras Monday. He had been in exile following a June 28 coup.

Honduras' de facto foreign ministry accused Brazil of 'interfering' in the country's internal affairs and of having turned its embassy into a 'subversion centre' used by Zelaya to incite his supporters to engage in violence and looting.

Brazilian officials stressed Thursday that they would not allow Zelaya to use their embassy for political purposes.
