UNITED NATIONS - Pakistan's letter to Secretary-General Ban Ki-moon on the deteriorating security situation along the Line of Control in the disputed Kashmir region has been issued as a document of the UN Security Council and distributed to all member states.

The letter was delivered to UN chief's office at UN Headquarters in New York by Pakistani Ambassador Masood Khan on Saturday. It was, in turn, transmitted to the secretary-general who was then in Cairo, by his office, and also to this month's Council President, Ambassador María Cristina Perceval of Argentina.

In the letter, Prime Minister's adviser on National Security and Foreign Affairs Sartaj Aziz drew attention to the escalation of Indian firing across the LoC and the Working Boundary between India and Pakistan, and sought UN intervention.

On Friday, the secretary-general issued a statement voicing his concern about the situation, and deplored the loss of lives and the displacement of civilians on both sides. He also encouraged India and Pakistan to resolve all differences through dialogue.
