( CNN ) -- A Chinese official accused `` Tibetan independence forces '' Tuesday of planning suicide attacks , an allegation that the Tibetan government-in-exile immediately denied . `` To our knowledge the next plan of the Tibet Independence forces is to organize suicide squads to launch violent attacks , '' Wu Heping , spokesman for China 's Ministry of Public Security , said at a news conference , according to a translation of his remarks by The Associated Press . `` They claim they fear neither bloodshed nor sacrifice , '' he said . He did not provide details or evidence , and Samdhong Rinpoche , prime minister of Tibet 's exiled government , dismissed the accusation . `` We never heard ( of ) Tibetan independence force , such a group or people . Now , our suspicion is that the PRC ( People 's Republic of China ) might be staging such a violent act in the name of Tibetan people to mislead the world community , '' he said in Dharamsala , India . Dharamsala is the center of the Tibetan community in India , where many Tibetans fled after a failed uprising against Chinese rule in 1959 and where the government-in-exile led by the Dalai Lama is based . `` It is our ... suspicion , otherwise there is no ground to claim that some Tibetan people or group is planning to ( use ) suicide bombers or something like that , '' the Tibetan prime minister said . There was no immediate response from the Chinese government to Rinpoche 's suspicion . In the U.S. State Department briefing on Tuesday , department spokesman Tom Casey said the United States did not share China 's concern that supporters of the Dalai Lama were plotting suicide attacks . The Dalai Lama is a `` man of peace , there is absolutely no indication that he wants to do anything other than have a dialogue with China to discuss how to deal with some of the serious issues there , '' Casey said . Beijing blames the Dalai Lama and his followers for violence that erupted amid protests for Tibetan independence last month . China has drawn international criticism for its crackdown on the demonstrations , which began peacefully on the 49th anniversary of a failed Tibetan uprising . The protests have threatened to throw a shadow on the Summer Olympic Games , being staged in Beijing in August . Tibet 's government-in-exile puts the death toll from the protests at about 140 , but the Chinese government restrictions make it difficult to confirm that number . Chinese authorities have reported a death toll of 19 , and say most of those killed were `` innocent victims '' -- Han Chinese targeted by Tibetans . Protests have spread across the globe with regular demonstrations in Nepal . A ceremonial lighting of the Olympic flame in Greece was also targeted by pro-Tibet activists .

Also on Tuesday , China 's official Xinhua news agency reported that the country 's foreign ministry urged the Dalai Lama to `` stop all separatist and sabotage activities if he really wants to contact and consult with the central government . '' Foreign Ministry spokeswoman Jiang Yu spoke in response to a March 28 statement from Dalai Lama . In that statement , the spiritual leader of Tibetan Buddhists said he does not seek the separation of Tibet and has no desire to `` sabotage '' the Olympic Games . `` Chinese brothers and sisters , I assure you I have no desire to seek Tibet 's separation . Nor do I have any wish to drive a wedge between the Tibetan and Chinese peoples , '' he wrote . Instead , he said , the protesters seek `` meaningful self-rule '' while remaining a part of China . `` Despite my repeated support for the Beijing Olympics , the Chinese authorities , with the intention of creating a rift between the Chinese people and myself , the Chinese authorities assert that I am trying to sabotage the games . '' He called on China to called `` to exercise wisdom and to initiate a meaningful dialogue with the Tibetan people . '' China offered some media organizations -- not including CNN -- a carefully managed tour of Tibet 's capital , but ran into a public-relations roadblock when a group of Buddhist monks began screaming protests at a holy shrine .
