U.S. President Barack Obama says the 10th anniversary of the September 11 terrorist attacks should be a National Day of Remembrance and Service.

During his weekly address Saturday, Mr. Obama urged the nation to honor the victims of the attacks with an act of service or charity.

The president says he and first lady Michelle will participate in a local service project, and he urged citizens to get involved by logging onto the website Serve.gov.

Mr. Obama is appealing to citizens to show the same compassion displayed after the September 2001 attacks, and volunteer their as the victims are remembered.

President Obama also said he and the first lady will be joining commemorations at New York's Ground Zero, in Shanksville, Pennsylvania and at the Pentagon. Nearly 3,000 people were killed during the terrorist acts at the three locations.
