Cambodia has decided to hold a week-long national mourning for its King Father Norodom Sihanouk, starting from October 17.

According to a directive signed on October 15 by Prime Minister Hun Sen, state and private offices as well as residential houses nationwide must have their state flags flown at half-mast during this official mourning period.

Cambodian embassies and diplomatic offices abroad organise the mourning ceremonies and keep funeral registered books open for guests to express their condolences.

The King-Father's body will be laid at the Royal Palace for at least three months for mourners to pay last respects before being cremated.

The former King Sihanouk was born on October 31, 1922. He suffered from various forms of cancer, diabetes and hypertension and had been treated by Chinese doctors in Beijing for years.

He died on October 15 in Beijing due to natural causes at the age of 90.

The current Cambodian King, Norodom Sihamoni, and Prime Minister Hun Sen are expected to bring the body of King-Father Norodom Sihanouk back to Phnom Penh on October 17.-VNA
