Biden aide Sullivan says Iran nuclear diplomacy may be exhausted in weeks

JERUSALEM, Dec 22 (Reuters) - The United States and its partners are discussing time frames for nuclear diplomacy with Iran, U.S. National Security Adviser Jake Sullivan said on Wednesday, adding that current efforts to achieve a new nuclear deal may be exhausted within weeks.

"We're not circling a date on the calendar in public, but I can tell you that behind closed doors we are talking about time frames and they are not long," he told reporters during a visit to Israel.

Asked to elaborate on the time frame, Sullivan said: "Weeks." (Writing by Dan Williams Editing by Jeffrey Heller)
