Authorities in Honduras have declared a state of emergency and imposed a 10-day curfew amid violent clashes triggered by claims of election fraud. At least one person has been killed and another 20 people injured in ongoing protests, with demonstrators burning tires, blocking roads and battling police. The unrest has prompted panic and looting, and some international flights have been suspended at the airport in Tegucigalpa. On Saturday, the country entered its sixth day without a declared winner from last week’s presidential election, as opposition leaders accuse the government of trying to manipulate the vote count. After a nearly two-day delay in vote tallying earlier this week, incumbent President Juan Orlando Hernandez had a lead of about 45,000 votes over his leftist opponent Salvador Nasralla with 94 percent of the vote counted late Friday.
