About 350 independent international observers would monitor the election, but only 90 had arrived, according to the electoral authorities.

The electoral authorities have established 5, 248 voting centers across the country, which will be guarded by two soldiers each.

Nevertheless, supporters of Zelaya, including unionists, students and farm workers, launched a boycott of the elections in the Central American nation.

On Saturday, de facto leader Roberto Micheletti told local radio HRN that the Sunday elections "will be the ones most observed," despite the fact that many from the international community will not recognize the outcomes.

He added that the armed forces and the police were ready to prevent any attack against the elections and urged the people to immediately report if they observe anything out of normal or irregular.

Nicaragua and El Salvador closed on Saturday their customs posts on the Honduras border and will open them again on Monday to avoid any possible incidents linked to Honduras' Sunday elections.

Zelaya was forced out of his country in the coup against him, which was condemned by the international community, and he has been staying in the Brazilian embassy in Honduran capital Tegucigalpa since late September.

He called on his followers to "impugn and denounce" the Nov. 29 elections while appealing to the international community not to recognize the outcome.
