Activist and CPI(ML) leader, Kavita Krishnan said Sarabjit was a "victim of lethal mix of communalism and jingoism" that drives state policy in the subcontinent.
"I condemn Sarabjit's murder. It is heinous violation of human rights by Pak State. An international probe is a must. Protect Indians in Pakistan jails. Culture of extra judicial killings of prisoners anywhere must stops," she said.
AAP National Convenor, Arvind Kejriwal also condemned the incident. "Sarabjit death leaves behind many questions," he said, adding this has shown that the government's priority was not the prisoner but to save corrupt people.
Union Minister Manish Tewari said that what happened to Sarabjit was "extremely inhuman and barbaric" since India has been pressing with Pakistan to take a humanitarian view in his case.
