UPDATE 1-Cambodia rights activist jailed 20 years on disputed conviction

(Adds statement from EU)

PHNOM PENH, Oct 1 (Reuters) - A Cambodian court jailed a

71-year-old radio broadcaster and land-rights campaigner for 20

years on Monday after finding him guilty of leading an

anti-state rebellion, a verdict condemned by activists as a

further crackdown on human rights.

Three judges in the Phnom Penh court convicted Sonando, who

has joint Cambodian-French citizenship, and 13 others of

inciting villagers in eastern Kratie province to rebel against

the government.

Sonando, a long-time rights campaigner and critic of Prime

Minister Hun Sen, stood accused of inciting villagers to take up

arms and of aiming to recruit up to a million people to topple

the government, charges his supporters say were trumped up.

Hun Sen urged in a nationally broadcast speech in June that

Sonando be arrested for masterminding "a plot to overthrow the

government and attempting to establish a state within a state".

Sonando, the head of Beehive Radio, had pleaded not guilty.

The number of land disputes in Cambodia has exploded in

recent years as the economy grows rapidly and companies move to

exploit natural resources such as rubber, sugar, and minerals.

Human rights groups have accused Hun Sen's authoritarian

government of riding roughshod over land rights by granting huge

economic land concessions to companies and then evicting

land-dwellers by force.

The World Bank froze new lending to Cambodia last year and

said it would not resume loans until the government did

something to help hundreds of families facing eviction from land

around a lake in Phnom Penh.

A spokesperson for the EU High Representative, Catherine

Ashton, said in a statement that the conviction "raises severe

doubts about the impartiality and independence of the court".

The EU has come under pressure from activists to freeze a

trade initiative that allows Cambodia to export goods

tariff-free to Europe. Critics say it has contributed to land

grabs in sectors such as sugar production.

Sonando's supporters say he was persecuted for criticising

the government. He raised a victory sign as he was led,

handcuffed, to a prison van after the verdict, saying he was

"proud".

Ou Virak, president of the Cambodian Center for Human

Rights, said the court had not produced any evidence to support

a guilty verdict.

"I am really disappointed that after many decades our court

is not a respectable institution that can find justice for

people," he said. "I see that the verdict was written by

politicians."

The court sentenced two other defendants to 30 and 15 years

in jail in absentia.

"Today's verdict only serves to demonstrate, yet again, that

the courts in Cambodia have been increasingly used as a tool for

repression," the International Federation for Human Rights said

in a statement.

The U.N. Human Rights Council's Special Rapporteur for

Cambodia said last week that Cambodia's population was growing

"increasingly desperate and unhappy" over land-rights abuses.

In recent months, one of Cambodia's leading environmental

campaigners was shot dead and a journalist who wrote about land

issues was found dead in the trunk of a car.

In Kratie province, a 14-year-old girl was killed in May

when security forces fired on villagers whom Sonando was found

guilty of assisting.
