Indian death row prisoner Kulbhushan Jadhav met his mother and wife at the Foreign Affairs Ministry in Islamabad today, Pakistani officials said.
"The meeting between Jadhav and his wife and mother has started," Pakistani officials said.
Mr Jadhav's wife and mother greeted the media after arrival but refused to respond to questions. They were accompanied by India's deputy high commissioner JP Singh and a woman Pakistani official.
Heavy security was deployed around Pakistan's Ministry of Foreign
Affairs.
Pakistani media reports said Pakistan Rangers, anti-terrorism squads and sharpshooters on rooftops around the ministry had been deployed.
The reports added that apart from security and media personnel, no other traffic is being allowed into the area.
Jadhav's wife and mother had landed in Islamabad a little earlier.
They flew in from Mumbai via Dubai and will return to India this evening itself via Muscat, Oman. They will spend a total of only seven hours in Pakistan.
