(CNN)  -- A new standoff was brewing in Honduras as the country's recently deposed president vowed to return, while the new provisional government said it would arrest him if he set foot back in the country.



Ousted Honduran President Jose Manuel Zelaya appears Tuesday at the U.N. General Assembly.



Political turmoil has swept this Central American nation of 8 million people following a military-led coup Sunday that ousted President Jose Manuel Zelaya. Troops entered the president's residence and sent him out of the country in exile. A veteran legislator, Roberto Micheletti, was sworn in that same day as provisional president with the support of congress.



Roberto Micheletti, the veteran legislator who was sworn in that same day as provisional president with the support of congress, was adamant that Zelaya would not return to power.



"He already committed crimes against the constitution and the laws; he can't return to be president of the republic," Micheletti told reporters Tuesday. "He can no longer return to the presidency unless a president from another Latin American country comes and imposes him with arms."



Micheletti added, "If there is an invasion against our country, we have seven-and-a-half million Hondurans ready to defend our territory and our laws and our homeland and our government."



However, Zelaya still vows to defy the provisional government.



"I am going to return on Thursday because they expelled me by force, and I am going to return as always: as a citizen and as president," Zelaya said at a U.N. news conference shortly after the world body unanimously adopted a resolution that he should be restored to power.



Zelaya, speaking to the U.N. General Assembly, called the resolution historic.



"Your servant has several accusations against him in Honduras," Zelaya said. "But nobody has given me a trial. Nobody has convened a tribunal."



Meanwhile, Micheletti's provisional government said Zelaya would be arrested if he returned.



"As soon as he arrives he will be captured, as we already have the arrest warrants ready," new Foreign Minister Enrique Ortez Colindres told CNN en Español.



Zelaya would face charges of violating the constitution, corruption and drug trafficking, among others, Ortez said.



The deposed president said he would travel to Washington to attend a meeting of the Organization of American States. He also is expected to meet Tuesday evening with Tom Shannon, the top U.S. official on Latin America.



Even as Zelaya spoke at the United Nations, his opponents held a large and noisy rally in Tegucigalpa, the capital of Honduras. Crowd members waved blue and white Honduran flags and signs denouncing Zelaya.



Roberto Micheletti, the new provisional president, briefly addressed the crowd Tuesday afternoon. He vowed that the next national elections, slated for November, will be held as planned, and that a new president will be sworn in as usual in January.



Gen. Romeo Vasquez Velasquez, the top Honduran military commander who had butted heads with Zelaya, also spoke at the rally. By removing Zelaya, the armed forces were only complying with their constitutional duties, he said.



Before he spoke, the crowd chanted in support, "Armed forces! Armed forces!"



Zelaya supporters also were active Tuesday, with three major public-sector labor unions launching a general strike, a union official told CNN. About 100,000 workers joined the strike, said Oscar Garcia, vice president of the Honduran water workers union SANAA. That number could not be independently verified.



"It will be an indefinite strike," Garcia said. "We don't recognize this new government imposed by the oligarchy, and we will mount our campaign of resistance until President Manuel Zelaya is restored to power."



Also on Tuesday, the U.S. State Department said it was reviewing its aid to Honduras as it works with regional partners on a deal to restore Zelaya to power and quell political unrest in the country.



State Department spokesman Ian Kelly said the U.S. was reviewing whether Zelaya's ouster met the legal definition of a "coup" before any decision was made.
