President Barack Obama has paid tribute to US forces at a ceremony at the military cemetery in Arlington, Virginia, on Memorial Day.

"Our nation owes a debt to its fallen heroes that we cannot ever fully repay. But we can honour their sacrifice, and we must."

Defence Secretary Robert Gates also paid tribute to the armed forces.

On Sunday, an annual motorbike rally and a concert in Washington DC were also part of the memorial celebrations.

Sarah Palin was among those who attended the rally, Rolling Thunder, although she did not address the crowds.
