Honduran President Manuel Zelaya, ousted in a military-backed coup four months ago, said today that a U.S.-brokered deal to end his nation's political crisis has collapsed.

Zelaya pronounced the week-old agreement a "dead letter" after de facto rulers formed a new "reconciliation government" without Zelaya's participation, as the deal had required.

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

Under the accord, Zelaya and the man who replaced him, Roberto Micheletti, agreed to let the Honduran Congress vote on whether to reinstate Zelaya to office, as the international community has been demanding. But congressional leaders, who backed the coup, have yet to call a vote.

The plan also required the formation by Thursday of a temporary "unity Cabinet" with representatives of both sides.

Just before midnight Thursday, Micheletti announced a new government that did not include Zelaya or any of his supporters.

Micheletti had signed on to the deal as a way to secure international recognition of presidential elections scheduled for Nov. 29. Most of the region's capitals had warned that elections overseen by a coup-installed government would not be deemed legitimate.

The failure of the accord hands an embarrassing setback to the Obama administration, which dispatched senior diplomats to settle the crisis a week ago but which has also sent mixed signals in opposing the coup, the first in Central America in 16 years. Washington had been firm in supporting reinstatement of Zelaya, but more recently seemed to wobble.

Micheletti said he consulted political parties and a "wide spectrum of civil society" to put together the new government. He did not publicly name the members. He said Zelaya did not propose any names but still could do so.

The army snatched Zelaya from his home June 28 and deported him to Costa Rica. Backers of the coup said they were acting to prevent Zelaya from illegally changing the constitution to allow for his reelection.

Zelaya, a timber tycoon whose turn to the political left alienated the Honduran elite, sneaked back into the country Sept. 21 and has been holed up ever since inside the Brazilian Embassy in Tegucigalpa, the capital.
