Sources said transmitters have come up across the Line of Control and the international border which blank out signals emanating from Thuraya phones used by terrorists. This makes it impossible for Indian agencies to triangulate and track the location of these Thuraya phones, which are among the most effective ways to detect infiltration or follow movement of known Pak-based terrorists.

India believes that these transmitters cannot exist without tacit support of the Pak establishment. And even if they do, they can easily be detected and removed. The existence of these transmitters, sources said, has provided another cover to terrorists acting against India. In fact, these phones were used by perpetrators of the Mumbai attacks.

Without being alarmist, the Indian security establishment feels there are “credible threats against India” even now. New Delhi’s main complaint is that Islamabad is not showing the kind of commitment it seems to display when it comes to dealing with terror groups operating against India compared to those active on its Western border.

Pak Interior Minister Rehman Malik has claimed the detention of five key suspects, including mastermind Zaki-ur-Rehman Lakhvi. But Lakhvi is still to be produced in court and India has received no evidence from Pakistan confirming his detention or arrest.

On the contrary, Indian agencies reported over a month ago that Lakhvi’s Thuraya phone was still moving around in Pakistan-Occupied Kashmir. While this, in itself, may not lead to anything conclusive about his status, it has only created doubts in the minds of Indian officials.

All this, along with the re-emergence of Jamaat-ud-Dawa under the banner of Falah-i-Insaaniyat, which parades itself as a humanitarian organization doing relief work among people displaced from the Swat valley, has put a question mark on the possibility of resuming the composite dialogue.

Recalling that today is the anniversary of the attack on the Indian embassy in Kabul, government sources said, the dialogue has been effectively on pause since then. They repeatedly stressed that the meeting of the Foreign Secretaries in Egypt will only take stock of the steps Pakistan has taken so far on not just the Mumbai attacks but on all other terrorist attacks in India aided by Pak-based groups. The meeting is slated for July 14 while PM Manmohan Singh will meet his Pakistan counterpart Yousuf Raza Gilani on July 16.
