Islamabad, Nov 10 (IANS): Two more staffers of the Indian High Commission in Islamabad on Thursday left Pakistan after being declared "persona non grata" for alleged spying, diplomatic sources told Geo News.

The two staffers turned out to be officials of India's Intelligence Bureau (IB), diplomatic sources said. They included First Secretary Press Balbir Singh and Jiabalan Sainthal.

Singh was reportedly the IB station chief while Sainthal too was a member of the agency in the guise of a staff officer.

The two officials left for India in wee hours of Thursday from Islamabad airport through on a foreign airline.

Earlier on November 8, three out of seven Indian High Commission officials, declared persona non grata by Pakistan, had left for home. They included First Secretary Commercial Anurag Singh, Vijay Kumar Varma and Mandhawan Nanda Kumar.

Pakistan had ordered expulsion of the eight Indian High Commission officials from Pakistan on charges of spying.

The remaining three officials of the Indian High Commission are also expected to leave Pakistan on Thursday morning through the Wagah border crossing.

On November 2, Pakistani authorities had claimed to have uncovered a spy network of Indian diplomats who were said to be involved in activities to destabilise Pakistan by facilitating and funding terrorism.
