Dharamsala, June 2 (IANS) Lobsang Sangay, prime minister of the Tibetan government-in-exile, Saturday expressed concern over the prevailing tense situation in Tibet and sought an end to human rights violations by China in the region.

As the self-immolations continue unabated inside Tibet, we Tibetans in exile are ever more concerned about the policies of the Chinese government in Tibet, he said here.

At least 38 people have reportedly killed themselves since 2009 in Tibet to protest Beijing's repressive policies and press for the return of the Dalai Lama to his homeland. He sought an end to alleged human rights violation by China in the Tibetan region.

Speaking at a prayer service here, Sangay said: We are holding this prayer service to pay homage to those who have sacrificed their lives for Tibet and console their family members.

He also spoke about the support extended by many world leaders and Nobel laureates for the cause of Tibet, and urged the Tibetans to continue to highlight the grim situation prevailing there.

The latest incident of self-immolation occurred May 30, when Rikyo, a mother of three, set herself afire in Zamthang, northeastern Tibet.

India is home to around 100,000 Tibetans.
