TEGUCIGALPA (Reuters) - Renewed negotiations to resolve Honduras' deep political crisis collapsed on Friday when representatives of ousted President Manuel Zelaya said they would no longer talk to the country's de facto government.

"As of now we see this phase as finished," Zelaya envoy Mayra Mejia said, referring to the dialogue shortly after midnight (2 a.m. EDT/0600 GMT).

Zelaya's camp earlier set an ultimatum for the caretaker government of Roberto Micheletti, who took power in a June 28 coup, to come up with a new offer but said there was no response.
