Cambodians mass in capital to mourn former king

The lavish funeral of Cambodia's revered former king Norodom Sihanouk will begin today. 

Officials are expecting more than a million mourners to throng Phnom Penh's streets. 

The late monarch died of a heart attack in Beijing in October, at the age of 89. 

His body will be paraded through the city atop a golden float shaped like a mythological bird, from the Royal Palace to an ornate, custom-built crematorium in a city park. 

Foreign dignitaries including Japan's Prince Akishino and a host of Asian leaders are due to attend the cremation.
