NEW YORK - Pakistan's Ambassador to the United Nations, Abdullah Hussain Haroon, returned to his post in New York Saturday after spending more than  three weeks in Pakistan attending to some personal matters. Haroon flew to Karachi on Oct 5 after President Asif Ali Zardari's visit to New York during which the Pakistani leader addressed the U.N. General Assembly. In his absence, Farukh Amil, the deputy Permanent representative, led the Pakistan delegation during a period when the assembly's 63rd session was at its peak, debating issues like the global financial and energy crises as well as other issues of war and peace on its agenda. Haroon, an affable man who had served as speaker of the Sindh Assembly, replaced Ambassador Munir Akram, a veteran of multilateral diplomacy, who relinquished the post at the end of August. The new ambassador took over his UN assignment on September 6.
