"I wrote a personal letter to Mr Sartaj Aziz for the grant of her visa to Pakistan. However, Mr Aziz has not shown the courtesy even to acknowledge my letter," she tweeted.
India also refutes Pak's claim of visa review for Jadhav's mother.
Osama Ali, a 24-year old resident of Rawalkot in PoK, has been diagnosed with a tumour in his liver and wants to seek treatment in Delhi. "PoK is an integral part of India. Pakistan has illegally occupied it. We are giving him visa. No letter required," Swaraj tweeted.
Jadhav was sentenced to death by a Pakistani military court in April on charges of espionage and terrorism.
Jadhav, 46, filed a mercy petition before Gen Bajwa last month, according to an Inter-Services Public Relations statement issued on June 22. The statement said that the former Indian Navy officer had filed the petition after the Military Appellate Court rejected his appeal.
