PORT-AU-PRINCE, Haiti -- Haitians are marking the second anniversary of the devastating 2010 earthquake with church services throughout the deeply religious country.

Women in white dresses and men in dark suits walked to church through streets were unusually quiet on what is a national holiday of remembrance.

Memorial services were planned at a U.N. base and the site north of the capital where thousands of quake victims are buried. President Michel Martelly is attending Thursday's opening of a new university with former U.S. President Bill Clinton.

The government has said the disaster killed 316,000 people and displaced 1.5 million. More than 500,000 are still in temporary settlement camps.
