UNITED NATIONS/ACCRA, Oct 24: Argentina’s foreign minister launched a diplomatic offensive in New York on Monday, urging top UN officials to pressure Ghana to release an Argentine naval training vessel seized after creditors won a court order to keep the ship in port. Foreign Minister Hector Timerman’s appearance at U.N. Headquarters came as sailors from the detained ship prepared to leave Ghana after spending weeks in dockside limbo, a government official said in Accra. (agencies)
