India News: Indian national Sarabjit Singh was in a "deep coma" and put on ventilator support after being assaulted by a group of prisoners in a Pakistani jail, with doctors on Saturday saying that they will not be able to perform surgery on him till his condition stabilises.

Sarabjit, 49, was in an Intensive Care Unit of the state-run Jinnah Hospital in Lahore, where he was admitted yesterday after being brutally beaten by at least six other prisoners within his barrack at the Kot Lakhpat Jail.
