Gunmen in Pakistan have reportedly shot dead the killer of Indian prisoner Sarabjit Singh. The identity of the gunmen and the motive behind the killing are still unclear. Sarabjit Singh, an Indian national, was convicted of spying in Pakistan and was sentenced to death. He was killed in 2013 while serving his sentence in a Pakistani prison, which strained the relationship between India and Pakistan. The recent killing of Singh’s killer raises questions about the security of prisoners and the state of law and order in Pakistani prisons.
