Leaders from Hugo Chavez to Barack Obama called for the reinstatement of Manuel Zelaya, who was arrested in his pajamas Sunday morning by soldiers who stormed his residence and flew him into exile.

Roberto Micheletti, appointed president by congress, insisted that Zelaya was legally removed by the courts and Congress for violating Honduras' constitution _ allegedly to extend his rule.

Zelaya's ouster was Central America's first coup in at least 16 years, a blow from the barracks that reminded many of the military dictatorships the region has tried to bury in its past.

Latin American leaders gathered in Nicaragua to draft a response, with all eyes on Venezuelan President Hugo Chavez, who said he would "overthrow" Micheletti.

Micheletti shrugged aside Chavez's threat, telling HRN radio on Monday: "Nobody scares us."

Micheletti said he was sure that "80 to 90 percent of the Honduran population is happy with what happened."

True or false, the rest of the world certainly was not, as the president of the U.N. General Assembly invited Zelaya to address the world gathering.

U.S. Secretary of State Hillary Rodham Clinton said U.S. diplomats were trying to ensure Zelaya's safety and get him restored as president, as well as "considering the implications" of the coup for U.S. aid.

But Clinton also hinted the U.S. wasn't entirely with Zelaya, urging an examination of "the underlying problems that led to yesterday's events."

The Organization of American States called for Zelaya's return and summoned a meeting of foreign ministers on Tuesday that could make Honduras the first nation suspended from the organization under a 2001 charter banning "the unconstitutional interruption of democratic order."

European Union officials offered to mediate talks between the two sides.

Chavez cast the dispute as an attempt by a wealthy elite to suppress the poor.

"If the oligarchies break the rules of the game as they have done, the people have the right to resistance and combat, and we are with them," Chavez said in the Nicaraguan capital, Managua.

Conservative Latin American governments also denounced the takeover. Mexico announced it was giving diplomatic protection to Zelaya's foreign minister, Patricia Rodas, who fled to Mexico City.

Zelaya was arrested and flown to Costa Rica hours before a rogue referendum he had called in defiance of Honduras' courts and Congress. His opponents claimed the vote was an attempt to remain in power after his term ends Jan. 27.

Micheletti said he would serve only until the end of Zelaya's term.

"We respect everybody and we ask only that they respect us and leave us in peace because the country is headed toward free and transparent general elections in November," Micheletti said.

His designated foreign minister, Enrique Ortez Colindres, told HRN that no coup had occurred. Ortez said the military had merely upheld the constitution "that the earlier government wanted to reform without any basis and in an illegal way."

Troops with riot shields surrounded the presidential palace and armored military vehicles were parked in front, but soldiers made no attempt to clear away about 200 pro-Zelaya protesters who were burning tires and other debris, as well as blocking streets with downed trees and billboards.

"We want our elected and democratic president, not this other one that the world doesn't recognize," said Marco Gallo, a 50-year-old retired teacher.

Most people in the capital went about business as normal. Nearly all businesses were open and traffic flowed normally aside from a small part of downtown Tegucigalpa.

The Honduran constitution limits presidents to a single four-year term and forbids any modification of that limit. Zelaya's opponents feared the referendum was part of an attempt to try to run again, just as other Latin American leaders have removed constitutional clauses designed to prevent strongmen from extending their rule.

The president of Latin America's largest nation, Brazil's Luiz Inacio Lula da Silva, said on his weekly radio program that his country will not recognize any Honduran government that doesn't have Zelaya as president "because he was directly elected by the vote, complying with the rules of democracy."

He also said Honduras risks isolation from the rest of the hemisphere.

"We in Latin America can no longer accept someone trying to resolve his problem through the means of a coup," Silva said.

U.N. Secretary-General Ban Ki-moon and the Rio Group, which comprises 23 nations from the hemisphere, also condemned the coup and called for Zelaya's return.

Zelaya said soldiers seized him in his pajamas at gunpoint in what he called a "kidnapping."

"I want to return to my country. I am president of Honduras," he said in Costa Rica before traveling to Managua on one of Chavez's planes for regional meetings of Central American leaders and Chavez's leftist alliance of nations, known as ALBA.

Coups were common in Central America until the 1980s, but Sunday's ouster was the first military power grab in Latin America since a brief, failed 2002 coup against Chavez.

It was the first military ouster of a Central American president since 1993, when Guatemalan military officials refused to accept President Jorge Serrano's attempt to seize absolute power and removed him.
