WASHINGTON (Reuters) - The United States and Israel showed signs of seeking to defuse tensions on Sunday ahead of a speech in Washington by Israeli Prime Minister Benjamin Netanyahu when he will warn against a possible nuclear deal with Iran.

Policy differences over the negotiations with Iran remained firm, however, as Netanyahu arrived in the United States on Sunday afternoon for a speech to Congress, which has imperilled ties between the two allies.
