Talks between the United States and Israel, aimed at healing a recent rift between the two sides, have ended with no sign of a breakthrough.
Israeli Prime Minister Benjamin Netanyahu left Washington after two days of meetings aimed at getting peace talks with Palestinians back on track.
He said some progress had been made, but no agreement was mentioned by either Mr Netanyahu or the White House.
The US admitted earlier differences remained between the two sides, following a row over Israel's plans to build homes in occupied East Jerusalem, the BBC reports.
Mr Netanyahu twice extended his visit in Washington to try to find a compromise.
The Israeli leader stayed on for another full day to meet the US Middle East peace envoy, George Mitchell, at his hotel.
Mr Mitchell returned to the US on Tuesday following a meeting in the West Bank with Palestinian Authority President Mahmoud Abbas.
Mr Netanyahu's meeting with US President Barack Obama came as authorities in Israel approved 20 new homes for Israeli Jews in occupied East Jerusalem.
Mr Obama urged Mr Netanyahu to take steps to build confidence in the peace process, a White House spokesperson said, and the US was seeking clarification of the latest plans to build homes in East Jerusalem.
Israel later issued a statement saying the decision for building permits was made in 2009 and reports that a new decision was made during the Washington talks was untrue, Reuters news agency reports.
Mr Netanyahu's trip came amid the worst crisis in US-Israeli ties for decades.
The dispute flared two weeks ago when, during a visit by US Vice-President Joe Biden, Israel unveiled plans to build 1,600 more homes in part of East Jerusalem, a move Washington branded an insult.
