ATHENS, June 5 (Reuters) - Greek police removed Tibetan activists who blocked the venue of an International Olympic Committee (IOC) conference in Athens on Thursday.

Police lifted the campaigners, who had lain down at the entrance to the venue, and moved them away. The activists shouted "Shame on the IOC" and "Tibetans are dying".

About seven members of the Students For a Free Tibet group, some draped with Tibetan flags, took part in the protest, demanding the IOC cancels the Olympic torch relay in Tibet and puts pressure on China on human rights.

"There is still time to do the right thing and cancel the Tibet leg of the torch relay," said head campaigner Han Shan.

Activists have caused serious disruptions to the Olympic torch relay ahead of the Aug. 8-24 Games in Beijing, protesting against a Chinese crackdown in Tibet, which China has ruled since a 1950 invasion.

The group, which has disrupted the torch relay from its start in ancient Olympia and on its route through European cities, said the IOC had not exerted any pressure on China or held it accountable for violations against Tibetans.

"The Chinese government is betraying the commitments it made to press freedom in its bid for the Games," Han Shan said.
