Pakistan on Monday alleged there were indications of anti-state elements in the country having links with India and said it would take up the matter with New Delhi.

"The issue (alleged links) will be taken up during the forthcoming meeting of the two countries on anti-terrorism mechanism," Foreign Office spokesperson Tasnim Aslam said at her weekly news briefing in Islamabad.

She, however, did not give details. To another question, she said Pakistan will also raise, during the composite dialogue process, the issue of India's opening of Siachen glacier for trekking.

"Pakistan will seek clarification from India on the issue as we are trying to find a solution to the Siachen problem," she said.

Aslam pointed out that Pakistan had made a number of workable proposals to India for resolution of the Siachen dispute and Prime Minister Manmohan Singh's [Images] statement in the recent past that a solution was imminent and that Siachen would become a glacier of peace raised hopes.

She said India's latest actions have disappointed Pakistan as these would vitiate the climate.

The spokesperson told another journalist that Kashmir or Siachen cannot be resolved through use of force.

The only way to make progress on finding a solution of these disputes is through dialogue, which the two countries are pursuing.

Asked to comment on remarks of a US think tank that Pakistani and Russian nuclear weapons are unsafe, the spokesperson said such reports are motivated and malicious.

Aslam said discussions with India are continuing on the gas pipeline from Iran, but Pakistan will go ahead with or without India because of its surging energy requirements.
