"Pakistan is considering the Indian request for the grant of visa to the mother of Kulbushan Yadav," state-run Radio Pakistan quoted Pakistan Foreign Office Spokesperson Nafees Zakaria as saying.

Kulbhushan is presently locked up in Pakistan, where he is facing spying charges and has been sentenced to death, only to be stayed by the International Court of Justice (ICJ) following India's successful appeal.

His mother Avantika had made repeated pleas earlier, which went unreciprocated by the neighbouring country.

Meanwhile, Pakistan's consideration comes days after being castigated by Indian External Affairs Minister Sushma Swaraj.

In her diatribe, Swaraj exposed Pakistan's lack of diplomacy and was severe on her counterpart Sartaj Aziz.

"We also have a visa application pending for an Indian national Mrs.Avantika Jadhav who wants to meet her son in Pakistan against whom they have pronounced a death sentence,' her tweet read.

"I wrote a personal letter to Mr.Sartaj Aziz for the grant of her visa to Pakistan," another tweet suggested.

"However, Mr.Aziz has not shown the courtesy even to acknowledge my letter," an ensuing tweet read.
