The interim government of Honduras and ousted President Manuel Zelaya have held informal talks in a bid to end the current political crisis, BBC reported.
Mr Zelaya said his meeting with an unnamed official was a positive first step, but little progress was made.
Interim Deputy Foreign Minister Martha Lorena Alvarado said the talks were not aimed at restoring Mr Zelaya to power.
Mr Zelaya remains holed up at the Brazilian embassy, which is surrounded by police and troops.
He has been sheltering there since making a surprise return to Honduras on Monday, after three months in exile.
A Brazilian diplomat told the BBC that those inside the embassy were being forced to survive on a diet of biscuits.
"I'm not saying that we are going to starve, but the situation is very precarious. We have no clothes, soap or towels," he said, adding that embassy staff were finding it very difficult to leave the building.
The United Nations Security Council is due to discuss the situation in Honduras on Friday, following a request from the Brazilian government.
