Argentine economy minister enters mediator's office: Reuters witness

NEW YORK (Reuters) - Argentina's Economy Minister Axel Kicillof arrived on Wednesday at the office of a New York-based mediator in a last-minute bid to thrash out a deal with holdout investors whose legal action risks toppling the country into default. A Reuters witness said Kicillof made no comment as he entered the building. Argentina has until the end of the day to clinch a deal or it will default on its debt for the second time in 12 years.
