India has sought an additional visa for Kulbhushan Jadhav's mother and a permission for her to meet the convicted spy after Pakistan offered to allow his wife a meeting on humanitarian grounds, a Foreign Office (FO) source told DawnNews on Saturday.

The FO only confirmed that it had received India's response to the offer and was looking into it.

In its response, India has expressed reluctance in sending Jadhav's wife alone to Pakistan and insisted that his mother's application is also processed, the source said.

India maintains that Jadhav's mother has a right to meet her son.

Pakistan had on Wednesday informed India that it would be willing to allow a meeting between the self-confessed spy and his wife "on humanitarian grounds".

The meeting would take place on Pakistani soil, the Foreign Office spokesman had told reporters.
