Pakistan state TV says a convicted Indian spy who was on death row has died from a head injury after two other inmates attacked him with a brick.

State TV announced Sarabjit Singh's death before dawn on Thursday.

Singh was attacked on Friday at a jail in the eastern city of Lahore and was later moved to a hospital for treatment.

Singh was arrested in 1990 for his role in series of bombings in Lahore and Faisalabad that killed 14 people. His family maintained he was innocent.

He was convicted of spying and carrying out the bomb blasts and sentenced to death in 1991. The sentence was later upheld by Pakistani superior courts.

Former military ruler Pervez Musharraf rejected his mercy petition in 2008.
