India's Prime Minister Manmohan Singh is demanding "justice" from rival Pakistan following the death of an Indian citizen who was jailed in Pakistan on spying charges.
Sarabjit Singh, who had spent 16 years in Pakistani prison, was reported early on May 2 to have died following an assault by fellow inmates at a jail in the city of Lahore.
He reportedly suffered a severe head injury when he was hit with a brick.
Singh had been convicted and sentenced to death over his alleged role in a series of bombings in Punjab Province in 1990 that killed 14 people. His family maintained he was innocent.
In a Twitter statement, India's Singh called on Pakistani authorities to bring to justice those responsible for what he called a "barbaric" attack on an Indian citizen.
