All the 22 people on board the crashed plane have died, Cambodian government spokesman and Information Minister Khieu Kanharith said on Wednesday.

Experts are trying to find the "black box" of the crashed plane, he told Xinhua by phone from Kampot province.

It was not a terrorist act, he said.

The bodies of the victims are to be sent to Phnom Penh soon, he added.

Cambodia's search helicopters spotted the wreck of the crashed aircraft at around 7 AM Wednesday on Mountain Bokor, Kampot province, aviation officials said.

Over 2,000 soldiers, including Prime Minister Hun Sen's personal bodyguard unit, have been searching the mountain area since Monday.

The U4 241 Flight from Cambodia's PMT Air flying from Siem Reapto Sihanoukville crashed on Mountain Bokor on Monday, the worst air accident in Cambodia in the past decade.

Among the people on board, 16 were tourists, with 13 from South Korea and three from Czech Republic, and the rest crew members.

Siem Reap and Sihanoukville are the top two tourist destinations of the kingdom.
