Pakistan's Foreign Office (FO) spokesman Qazi Khalilullah said at that he had seen media reports about arrests but "Indian authorities have not approached us in this regard".
The role of a Pakistan High Commission employee in New Delhi has come under the scanner in connection with an espionage racket in which an alleged ISI operative and a serving BSF personnel have been arrested by the Delhi Police.
"We reject allegations against the High Commission and our premier intelligence agency. They are baseless and unfounded. Such allegations leveled against our intelligence agency in the past have proved to be false," he said.
"We have to wait and see. Pakistan has always emphasised the need for a sustained and result oriented dialogue to discuss all issues, resolve outstanding disputes including Kashmir and promote bilateral cooperation with India," he said.
Khalilullah said that foreign ministers of China, Tajikistan, Kyrgyzstan, Iran and Afghanistan have confirmed participation in the Heart of Asia conference here next week.
He said that the confirmation list is being updated on a daily basis.
Khalilullah said the conference will be jointly inaugurated by the Pakistan premier and the Afghan president.
The spokesman denied any footprint of IS in Pakistan and promised action if its presence was detected as part of its commitment to eliminate terrorism from the country.
"We have also been extending cooperation to the international community in eliminating terrorism. This includes exchange of intelligence. We support coordinated action against terrorists," he said.
