Honduras has given its army and police more powers to contain unrest following violent protests over last Sunday’s disputed presidential election.
Government official Ebal Diaz said “constitutional guarantees” had been suspended and a curfew imposed.
Earlier, the publication of election results was delayed when the main opposition candidate demanded more than 5,000 ballot boxes be recounted, the BBC reports.
Salvador Nasralla said he has evidence of electoral fraud.
Violent demonstrations since the election have left one person dead and 20 injured.
Riot police fired tear gas at angry opposition supporters in the capital Tegucigalpa on Friday, near the centre where the results were due to be announced.
Elsewhere, protesters blocked major roads and set vehicles alight.
“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,” Mr. Diaz said on national television.
He said a curfew would be in place between 18:00 and 06:00 for the next 10 days.
