WASHINGTON, Dec 10 (Reuters) - US Secretary of State Hillary Clinton will tell Israel and the Palestinians on Friday that Washington is committed to peace but it is their responsibility to end their conflict, the State Department said on Friday.

She will make clear that the United States remains committed to this process but that responsibility to end the conflict ultimately rests with the parties themselves, State Department spokesman P.J. Crowley told reporters, referring to a speech Clinton is due to give at 8 p.m. EST on Friday (0100 GMT on Saturday).
