"There would be a partition for security reasons", a Pakistan foreign ministry official said when asked whether the family members would be allowed to meet Jadhav personally.
"This meeting was not consular access as we had told India that its diplomat would see the meeting but was not allowed to speak or participate in it", Faisal told reporters.
Accompanied by Deputy High Commissioner JP Singh and a Pakistani woman official, TV footage showed Jadhav's family entering the main building of the Ministry of Foreign Affairs (MoFA) and the door shutting behind them.
Foreign Office Director India desk Dr Fariha was also present at the meeting, which was videographed.
Faisal also tweeted that the meeting was arranged in light of "Islamic traditions and based on purely humanitarian grounds". "This was conveyed to Indian High Commission categorically", he said.
Jadhav met his wife and mother at the Foreign Office for around 40 minutes, but interacted through a glass panel and intercom.
This is the first meeting between Jadhav, who was convicted of espionage, and his family since his arrest on March 3 a year ago.
This was the first meeting between Jadhav, who was convicted of espionage, and his family since his arrest on March 3, 2016. Twenty-two months since Kulbhushan Jadhav was taken into illegal detention in Pakistan, his family will finally get a glimpse of him on Monday.
The meeting started at around 1.35 pm and lasted about 45 minutes, after which the entire party re-emerged, and were driven away in a white SUV.
He said Pakistan has concrete evidences against Kulbhushan Jadhav of his involvement in subversive activities in Balochistan and Karachi.
"We wanted to know why he was using fake passport and use it to enter India at least 17 times". Television footage showed a convoy of around seven vehicles escorting Jadhav's family after they arrived in the city.
"The meeting was very positive and they (Jadhav's mother and wife) were satisfied".
A military court sentenced Jadhav to death in April for espionage and terrorism against Pakistan. In India, officials however downplayed the comments by the Pakistani minister, maintaining that an Indian diplomat was only accompanying Jadhav's family and it can not be construed as "consular access".
The ICJ suspended the execution, pending final judgment by the court.
