ISLAMABAD Foreign Minister Shah Mahmood Qureshi will be representing Pakistan in a special session of UN General Assembly to be held on 19th of August in New York. UN has called a special session of General Assembly to discuss situation in Pakistan after worst ever flood played havoc across the country, Qureshi told reporters during a press conference here on Monday. UN chief Ban Ki-moon and US Secretary of State Hillary Clinton would address the session. Qureshi further told reporters that NATO officials had reached Pakistan and were busy in talks with Government officials in Islamabad on setting up an 'air bridge to provide relief by means of air transportation to millions of Pakistanis affected by the devastating floods. Many flood-hit areas were inaccessible by road and the only way to provide relief to them was through helicopters, Foreign Minister Shah Mahmood Qureshi added. A six-member NATO team is in Islamabad to discuss modalities for the air bridge and to assess Pakistans needs, he said. It is the second time NATO is engaged in relief efforts in Pakistan, following the 2005 earthquake, which killed more than 73,000 people and left around 3.5 million people homeless. The NATO team held talks with officials in the Foreign Office today to assess Pakistans needs and to discuss the establishment of an air bridge for relief goods, Qureshi told reporters during a press conference on Monday. Answering a query, the Foreign Minister said Japan had also sent a team to Islamabad to assess our needs and to provide helicopters in the ongoing relief and rescue operations. Qureshi spoke highly of the International community for its quick response, he said Pakistan had to sensitise them about the scale and magnitude of the disaster. This is an unprecedented flood and international effort should also be unprecedented, he said. Describing the devastations caused by the floods as the worst humanitarian crisis in the world today, he said the three-week long disaster had affected 20 million people and destroyed crops, infrastructure, towns and villages. The United Nations has launched an aid appeal of 460 million dollars, but charities say the response has been sluggish and flood survivors on the ground have lashed out against the weak civilian Government for failing to carry out relief activities effectively.
