Pakistan on Thursday warned India that it would give a 'suitable reply' if New Delhi extended the US doctrine of pre-emptive strike against it.

"Pakistan wants peaceful solution of all issues, including Kashmir, but India should realise that Pakistan's armed forces and its people can give a suitable reply to any aggression committed against their territory," foreign office spokesman Aziz Ahmad Khan said.

Khan was reacting to External Affairs Minister Yashwant Sinha's reported remarks that India has better case for a pre-emptive strike against Pakistan than the US had against Iraq.

Khan accused Sinha of making 'irresponsible' statements in recent times.

"They should realise that India is not the United States nor Pakistan like Iraq," Khan said.

He said the theory of pre-emptive strikes 'is not recognised by the UN charter, which only recognises the right of self defence in case of outside aggression.

Khan also denied India's charges of promoting cross-border terrorism and sought UN observers to be posted along the Line of Control to verify the accusations.

In another development, Pakistan has written to London-based Amnesty International to investigate the recent massacre of Kashmiri Pandits in Jammu and Kashmir.
