United States gave US$139 millions under the Food Aid Program to Pakistan on Mr Gilani's recent visit to USA. But lets just count this as only US$ 39millions because our government is paying US$100 millions to United Nations as the cost of a UN investigation in Benazir's murder. I thought we did not need this investigation because we already know who murdered her. Mr Gilani has said in US "Our leader, Benazir Bhutto, was killed by militants". Case closed. I don't know why we are paying this US$100 millions to UN? -SAJID ANSARI, Karachi, via e-mail, August 7.
