Mother Teresa's home of the dying

This week marks 100 years since the birth of Mother Teresa - the Catholic nun who dedicated her life to humanitarian missions in India as well as more than 100 other countries. Her most famous project is a centre in the Indian city of Kolkatta that gives food, shelter, and care to the critically ill poor that can not afford hospital treatment. But what has been called the "home of the dying" is also one of Teresa's most controversial missions, as Prerna Suri reports. [August 25, 2010]
