Haiti is marking the fifth anniversary of a devastating earthquake with an early-morning church service and a gathering of dignitaries at a mass grave.

This is an official Day of National Remembrance in the impoverished country. Hundreds of Haitians started the day in their best clothes at a new Catholic church in downtown Port-au-Prince. The church replaced the cathedral left in ruins by the earthquake that also leveled much of the capital and surrounding area on Jan. 12, 2010.

People who attended the Mass said they are still grieving over their losses from a quake the Haitian government said killed more than 300,000 people and left more than 1 million homeless.

President Michel Martelly was presiding at a memorial Monday at a mass grave north of Port-au-Prince.
