Dr Singh, however, told a joint press conference with British Prime Minister David Cameron that he looked forward to Mr Qureshi's visit to New Delhi later this year to continue the important dialogue with Mr S.M. Krishna.

Saying it was still too close to the event to pass a judgment on the meeting, Dr Singh added “The way the press conference was handled by Pakistan foreign minister could have been avoided because it detracts from larger elements of agreement reached.”

He also said that after 9/11, the world community had realised that terrorism constituted a serious threat to civilised societies of the world and no cause could justify it.

“I sincerely hope that the government of Pakistan will honour its commitments given to me and my predecessor that Pakistan will not allow its territory to be used for terror activities,” Dr Singh said.

Mr Cameron reiterated that his country “will not accept any terror group within Pakistan”. He said “We will encourage Pakistan to crack down on terror groups.”

He also said “We will discuss with the Pakistan leadership frankly, clearly and openly on steps to contain terror from its soil.”

But, Mr Cameron also told Dr Singh that “we must be fair to Pakistan, as they have taken anti-terror steps”.

India's main opposition Bharatiya Janata Party had criticised Mr Krishna for pinning the blame for the Islamabad fiasco on a home ministry official who had claimed the ISI's involvement in the Mumbai terror attack. Mr Qureshi had objected to the remarks that were made ahead of Mr Krishna's visit.
