Clinton: window for Iran talks can't stay open 'too much longer'

WASHINGTON, Jan 31 (Reuters) - The window for negotiations with Iran about its nuclear program cannot stay open for "too much longer," outgoing U.S. Secretary of State Hillary Clinton said on Thursday but she declined to provide a deadline.

"I don't think the window can remain open for too much longer (but) I am not going to put days, weeks or months on it," Clinton told a small group of reporters on her second-to-last day as the chief U.S. diplomat. (Reporting By Arshad Mohammed; Editing by Sandra Maler)
