"He was very critical and suffered a cardiac arrest early in the morning. Despite our best efforts, he could not survive and was declared dead around 7.30am," said a senior doctor treating him.
Yeshi had set himself ablaze near Jantar Mantar on Monday afternoon and was rushed to the hospital.
He is the 31st Tibetan who died after committing self-immolation in Tibet and in India.
Yeshi had been living in the old camp of Majnu Ka Tila in Delhi for the last two years and was the youngest of five siblings. Born in Kham Tawu region in Tibet, he escaped to India in 2006 and studied at the Tibetan Transit School in Dharamshala for nearly three-and-a-half years.
