Reporting from Mexico City-- The political crisis in Honduras deepened Friday after ousted President Manuel Zelaya declared "totally dead" a U.S.-brokered agreement that he had believed would restore him to power.

Zelaya, deposed in a military-backed coup four months ago after ignoring a court order to stop efforts to hold a referendum on revising the nation's constitution, said the accord collapsed after the de facto rulers formed a new "reconciliation government" without him.

The week-old deal had sought to bring representatives of Zelaya and his enemies into a transitional government as a way to ease the crisis and legitimize elections scheduled for Nov. 29.

"The accord is a dead letter," Zelaya said on a Honduran radio station. "There is no sense in continuing to fool the Honduran people."

He called on supporters to take to the streets and to boycott the vote, which he deemed a "fraud" designed to "whitewash" the coup.

In Washington, officials who sponsored what had been hailed as a breakthrough and "victory for democracy" said they were disappointed by the setback.

"We urge both sides to act in the best interests of the Honduran people and return to the table immediately to reach agreement on the formation of a unity government," said U.S.
