With the thaw in its relations with India, Pakistan has suggested that all 947 prisoners currently held in jails in both countries be release as part of the bilateral peace process.
Pakistan had offered to release all Indian prisoners held by it in exchange for Pakistanis held in Indian jails, an official here said.
"But so far we haven't received any response to our proposal (from India)," the official said.
"Of the total of 350 Pakistani prisoners in Indian jails, there are 247 civilian prisoners and 103 fishermen. Among the 597 Indian prisoners in Pakistani jails, there are 406 fishermen and 191 civilian prisoners," he said.
The official said that the offer for the release of the prisoners was made during the talks between the two countries this month. India and Pakistan held several rounds of talks in August as part of their composite dialogue process.
Official sources said of the 247 Pakistani civilian prisoners in Indian jails, the interior ministry had confirmed the nationality of 123.
The ministry is yet to confirm the nationality of 54 prisoners of Pakistani origin. "The remaining 70 Pakistani civilian prisoners in India have not yet been provided consular access by Indian authorities," a source said.
"Of the 191 civilian Indian prisoners, the nationality of 41 has been confirmed and they will be released soon along with Indian fishermen as announced by the interior secretary during the Pakistan-India talks on terrorism," the source said.
The sources said a majority of civilian prisoners detained in jails in both countries were those who crossed the border by mistake.
Many prisoners had completed their jail terms but were still behind bars either because of the non-availability of surety bonds or because their respective country had not confirmed their nationality, the sources said.
