President-elect Barack Obama pays an emotional tribute to his grandmother as he scatters her ashes at a Hawaiian beauty spot.

Obama stood alongside his half-sister Maya Soetoro-Ng as they paid their last respects to Madelyn Dunham, who died of cancer at the age of 86, just two nights before her grandson was elected president.

Together they were seen scattering the ashes into the water at the Lanai Lookout, a scenic area of coastline on the southeast corner of Oahu, Hawaii today.

The area was the same place that Obama scattered his mother's ashes following her death more than 10 years ago.

Obama - casually dressed and wearing sunglasses - had earlier attended a memorial service for his grandmother at the First Unitarian Church in Honolulu.
