Khurshid says he is anguished by Sarabjit's death

External Affairs Minister Salman Khurshid today said he was "extremely anguished" by the death of Sarabjit Singh in a Lahore hospital following a brutal attack on him in a high-security jail.

"We are extremely anguished by the death" of the Indian prisoner, Khurshid told reporters when asked to react to the death of Singh.

Sarabjit died of cardiac arrest in a Pakistani hospital in the wee hours today after being comatose for nearly a week following a brutal assault by fellow inmates in a high- security jail.

The Indian prisoner had sustained severe injuries when at least six prisoners attacked him in a barrack at Kot Lakhpat Jail on Friday last.
