Kashmiri separatists Syed Ali Shah Geelani and Shabir Shah were reportedly put under house arrest once again on Friday after Pakistan made it clear that its National Security Adviser Sartaj Aziz will go ahead with the meeting proposed with the leaders of Hurriyat factions in New Delhi on 23 August.

According to TV reports, the separatist leaders' detention came soon after Pakistan government sources said it will not take any dictation from India and the talks between Aziz with Indian NSA Ajit Doval will not be based on conditional diplomacy.

On Thursday, Hurriyat hardline faction chief Geelani and another separatist leader Mirwaiz Umar Farooq were detained and put under house arrest, but were released after a couple of hours.

Pakistan had on Wednesday sent invites to Hurriyat representatives for a "reception party" at its high commission in New Delhi with Aziz.

"India has advised Pakistan yesterday that it would not be appropriate for Mr Sartaz Aziz to meet with Hurriyat representatives in India," Ministry of External Affairs (MEA) spokesperson Vikas Swarup tweeted on Friday.

The NSAs of the two conutries are scheduled to meet in New Delhi on Monday, 24 August, with terrorism-related issues and continuous ceasefire violations at the LoC as the likely agenda.

In 2014, India cancelled talks between the foreign secretaries of the two nations after Pakistani envoy Abdul Basit met with Hurriyat leaders.
