TIBET: Nearly 140 people have been killed in a crackdown by China's government since protests against Chinese rule started in Tibet, it is claimed.

The Tibetan government-in-exile named 40 Tibetans killed since the protests started in the Tibetan capital of Lhasa.

It said about 100 others also have been killed.

The riots and protests, the largest and most sustained in almost 20 years, have angered Beijing.

They have also drawn attention to the country's human rights record ahead of the Beijing Olympics in August.

Yesterday's lighting ceremony in Greece to mark the start of the Beijing Olympics torch relay was marred by protests.

Two demonstrators ran on to the field at Ancient Olympia during the ceremony, which was carried on Chinese state television with more than a 30-second delay.

Cameras abruptly cut away when a man carrying a banner ran behind Liu Qi, the president of Beijing's Olympics organising committee.

A Tibetan woman covered herself in red paint and lay in the road in front of a runner carrying the Olympic torch.

Beijing's official death toll from the protests in Lhasa is 22, including civilians killed in rioting and three Tibetan suspects who jumped to their deaths to avoid arrest.

Protests started on March 10 in the Tibetan capital of Lhasa on the 49th anniversary of a failed uprising against Chinese rule.
