ISLAMABAD - Advisor to Prime Minister for Foreign Affairs and National Security Sartaj Aziz on Tuesday sounded pessimism about the prospects of Nawaz Sharif's upcoming meeting with Indian counterpart on the sidelines of UN session.

Talking to media persons here, Sartaj Aziz said that there was no contact between Pakistan and India regarding the meeting of Nawaz-Manmohan on the occasion of UN General Assembly meeting.

"No ice melting is seen in Nawaz-Manmohan meeting" he remarked. He said that Kashmir issue must be resolved in the light of the UN resolutions. To a question, he said that India had not allowed cross-examination of the accused in Mumbai attacks case.

He said that non-state actors could be involved in LoC firing incidents and they might be using Pak Army uniform. Sartaz Aziz said that relations between Pakistan and India were tense in past few weeks due to recurrence of firing incidents at LoC and ceasefire violations by the Indian forces. He said that Pakistan would release Afghan Taliban leader Mullah Baradar but he would not be handed over to Afghan authorities.

He said Minister for Petroleum Shahid Khaqan Abbasi is to pay a visit to Iran in the near future to discuss the Iran-Pakistan (IP) gas pipeline project.

He reiterated that Islamabad will pursue the project and has informed the US of its energy requirements. Pakistan is bound to purchase Gas from Iran by January 1, 2015.

Iran and Pakistan officially inaugurated the construction phase of a gas pipeline project in March which is due to take Iran's rich gas reserves to the energy-hungry South Asian nation.
