Islamabad: Pakistan said on Thursday that it was considering India's request to grant a visa to the mother of Kulbhushan Jadhav, the alleged Indian spy.

Foreign Affairs Ministry spokesperson Nafees Zakaria, however, regretted that India had imposed strict restrictions on the grant of visas to Pakistanis seeking medical treatment in India, the Nation daily reported.

Indian External Affairs Minister Sushma Swaraj on Monday complained that Pakistan was yet to give a visa to Jadhav's mother.

She said she had personally written to Pakistan Foreign Affairs Advisor Sartaj Aziz regarding a visa to Avantika Jadhav, who wanted to meet her son languishing in an unknown military prison in Pakistan.

Pakistan says Jadhav was arrested from Balochistan province in March 2016 and alleged he was involved in spying and terrorist activities. He was convicted in April by a Pakistani military court and sentenced to death.
