TEGUCIGALPA, Dec 1 (Reuters) - Honduras suspended the right to free movement on Friday, imposing a dusk-to-dawn curfew and giving the army and police extended powers after looting and protests triggered by a contested election killed at least one person.

Five days after polls closed, no clear winner has emerged from Sunday's vote. President Juan Orlando Hernandez has clawed back a thin lead over his challenger, but thousands of disputed votes could still swing the outcome.

At least one protester has died, over 20 people were injured and more than 100 others were arrested for looting after opposition leaders accused the government of trying to steal the election by manipulating the vote count.

"The suspension of constitutional guarantees was approved so that the armed forces and the national police can contain this wave of violence that has engulfed the country," said Ebal Diaz, member of the council of ministers.

International concern has grown about the electoral crisis in the poor Central American country, which struggles with violent drug gangs and one of the world's highest murder rates. Honduras is the source of waves of poor migrants to the United States and sits on major cocaine trafficking routes.

The nationwide curfew will run from 6 p.m. to 6 a.m. for 10 days starting on Friday night, government minister Jorge Ramon Hernandez read out in a statement simultaneously broadcast to TV and radio stations.

Under the decree, all local authorities must submit to the authority of the army and national police, which are authorized to break up blockades of roads, bridges and public buildings.

In the widely criticized vote count, TV-host's Salvador Nasralla's early lead on Monday was later reversed in favor of President Hernandez, leading Nasralla to call for protests.

One of the four magistrates on the electoral tribunal on Thursday flagged "serious doubts" about the counting process.

Nasralla, who heads a center-left coalition, said government infiltrators had started the looting and violence to justify a military curfew.

"The people doing acts of vandalism are not from the opposition Alliance, they are from the government," Nasralla said on his Facebook page. "These are government operations to spread panic, create chaos and make you believe that the Alliance is causing the destruction."
