Argentina asked a United Nations court on Thursday to order the immediate release of a tall ship naval training vessel being held in Ghana, west Africa at the request of holders of Argentine bonds which they say are due for repayment, Reuters reported. The Ghanaian authorities detained the sailing frigate ARA Libertad in the port of Tema on Oct. 2 at the request of hedge fund NML Capital Ltd, which says Argentina owes it $300 million on bonds which have been in default since 2002. Last week creditors won a U.S. court ruling ordering Argentina to pay $1.3 billion to sovereign bond holders who had shunned debt restructuring deals in 2005 and 2010. -- SPA
