Thousands of supporters of leftist Honduran presidential candidate Xiomara Castro marched peacefully in the capital Sunday to demand a recount of the ballots cast in last week's election.
Castro, the candidate of the Libre Party, lost the election by 8 percentage points to conservative ruling National Party candidate Juan Orlando Hernandez.
Speaking to supporters, Castro vowed to continue to fight for a re-count.
International observers monitoring the election said the balloting process was conducted without irregularities.
Castro and her husband, toppled ex-president Manuel Zelaya, appeared at the peaceful demonstration alongside the coffin of Libre party activist Antonio Ardon. Libre officials say Ardon was shot in the capital Saturday by four unknown gunmen.
Honduras, known as the murder capital of the world because of its soaring homicide rate, is one of the poorest countries in the Western Hemisphere.
