ISLAMABAD - Dr Khalil Chishti has reached Pakistan after spending 20 years in an Indian jail.
Chishti is an 80-year-old Pakistani virologist who spent at least 20 years at a prison in Ajmer, India. 
The Indian Supreme Court had permitted Dr Chishti to visit Pakistan during the pendency of his appeal against his conviction in a murder case and life imprisonment.
“I am happy that I have arrived in my country. I am happy to meet my family and friends. It was my longstanding desire to offer prayers on reaching my motherland, ” said emotionally-charged Chishti on arrival.
Dr Chishti said that he would also go to Lahore to meet Sarabjit Singh, the Indian national facing death sentence on charges of involvement in bomb blasts in Pakistan. A special plane sent by President Zardari brought Chishti back. The President has taken up the issue with Indian authorities during his last visit to India.
