Ceremonies were held in Haiti on Wednesday to commemorate the first anniversary of the devastating 7.0-magnitude earthquake that killed more than 250,000 people. The national flag was lowered at the destroyed presidential palace.
Traffic in the normally bustling streets of the capital, Port-au-Prince, came to a standstill as people reflected on the disaster. Some visited the graves of relatives.
Thousands of others congregated at the remains of the nation's main cathedral.
Practitioners of voodoo, Haiti's traditional religion, also held ceremonies to commemorate the anniversary.
During the minute of silence at 1653 (2153 GMT) - the exact moment the earthquake struck - many people held their arms aloft in grief.
Services were also held by Haitians abroad. A survivor of the earthquake, Melissa Etinne, lit a candle for one of the 10 Roman Catholic dioceses in Haiti during a service at the Cathedral of Saint Mary in Miami.
Former US President Bill Clinton, the UN envoy for Haiti, and Haitian President Rene Preval attended a ceremony to lay the first stone for a memorial park in the centre of Port-au-Prince.
One year on, more than 800,000 people are living in makeshift camps, and up to 8,000 a month are seeking life-saving treatment for cholera.
A BBC correspondent in Haiti says there is much despair at what seems to be a lack of progress in rebuilding the country. Some blame weak government, others the aid agencies.
