Honduras: President Juan Orlando Hernandez declared election victor

Former Honduran President Manuel Zelaya, who backed Nasralla, took to Twitter, saying Hernandez "is not our president" and urging people to take to the streets in protest.

Nasralla and the opposition have claimed the November 26 presidential vote was marked by fraud and irregularities.

They will not be able to "stop the people who are going to continue with the peaceful demonstrations to defend their popular will expressed in the ballot boxes", he added.

"This means the president-elect for the Republic of Honduras for the next four years is Juan Orlando Hernandez Alvarado", David Matamoros, the head of the tribunal, said in a nationally televised address.

A senior Honduran government official ruled out a new presidential election on Monday, the day after the Organization of American States called for one following a contentious vote that has sparked violent protests. "The TSE of Honduras imposes a fraud in favor of Juan Orlando Hernández, we absolutely reject the TSE's statement".

He said the election was marred by irregularities and deficiencies and called for a new general election.

Nasralla has alleged fraud and is not recognizing the results, and the Supreme Electoral Tribunal has not yet declared a victor.

John Creamer, U.S. deputy assistant secretary of state for the Bureau of Western Hemisphere Affairs, told Nasralla the State Department was studying both the OAS and European Union reports and did not speak in favor of or against new elections, Tony Garcia, an adviser to the candidate present in the meeting, told Reuters. The tally has been questioned by the two main opposition parties and a wide swathe of the diplomatic corps.

TV broadcast images of protesters setting up flaming barricades and blocking roads in cities around the country.

Once results started flowing in again, Nasralla's lead began narrowing and eventually disappeared.
