Indian death row prisoner Sarabjit Singh died of cardiac arrest in a Lahore hospital in the wee hours on Thursday after being comatose for nearly a week following a brutal assault by other inmates of a high-security jail.

Sarabjit's death has angered the nation and political parties have demanded strict action against Pakistan.

Here are the latest updates in the case:-

10:15 am: The Pakistani establishment must account for Sarabjit's death, Tewari says, and adds what has happened is extremely inhuman, barbaric and it is not the way a civilized state treats their prisoners.

10:15 am: An Indian citizen has been murdered in cold blood in the custody of the Pakistani state, says Manish Tewari of the Congress.

10:05 am: Sarabjit's is not a death but a murder. No human rights or rule of law exists in Pakistan and our government has also faltered in dealing with Islamabad, says Meenakshi Lekhi of BJP.

10:00 am: He wasn't guilty and not even released on humanitarian grounds; the development is very unfortunate, it seems to be a conspiracy, says SGPC president Avtar Singh Makkar.

9:55 am: This is not just a death but a murder, adds Alvi.
