NEW DELHI - PAKISTAN has deployed some additional troops along the border with India since the Mumbai attacks, but India has not responded in a similar manner, the Indian army chief said on Wednesday.

'The aspect of some (Pakistani) troops coming towards the east...we are aware. That has happened,' General Deepak Kapoor told reporters. 'They have come to the eastern border of Pakistan with India.'

Pakistan's military has denied any build-up of forces on the Indian border and said it moved a 'limited number' of soldiers off the Afghan border 'for defensive measures' as tensions rose with India after the Mumbai attacks.

A near-daily exchange of tough words since the attacks has added to the tension as India has tried to pile up international diplomatic pressure on Pakistan.

A senior Indian official also confirmed on Wednesday 'some' troops movement on the Pakistan side, but added New Delhi had been careful not to respond in a similar fashion.

General Kapoor said though India was not provoked and would not indulge in whipping up war hysteria, its armed forces were in a state of full preparedness.

'Let me assure you the Indian army has factored this part in its planning, if at any time, any operations have to be undertaken,' he said.

'That is not something which is a cause of concern for us.

'(That) we in India are keeping all our options open must be clearly understood. It is not to raise any kind of hysteria for any kind of war, fight or anything.' -- REUTERS
