Barack Obama warned Donald Trump that sweeping policy changes in the Middle East would have "enormous consequences" as he delivered his final press conference as president.

He said he feared "the moment may be passing" for a two-state solution between Israel and the Palestinians, which had been one of the goals of his two-term presidency.

The president said that he stood by the decision last month to allow a UN Security Council resolution to pass criticising Israel over the growth of Jewish settlements in Palestinian territories - a move widely condemned by the incoming Trump administration.

Mr Obama warned Mr Trump against any "sudden, unilateral moves" on the conflict, two days before handing the presidency over to the Republican.
