US President-elect Donald Trump has lashed out at the UN, describing the world body as a "club for people to get together, talk and have a good time".
"The United Nations has such great potential but right now it is just a club for people to get together, talk and have a good time. So sad!" Trump tweeted.
Trump's remarks come following a decision by President Barack Obama to abstain from a UN Security Council vote condemning Israel's settlements in the West Bank and parts of Jerusalem. The abstention marked a historic change in policy that permitted the resolution to pass.
Ahead of the vote, Trump had publicly asked the US to veto the resolution.
The Washington Post said Trump's tweet "signalled" that he would "likely challenge more than just the 71-year-old institution's approach to the Middle East once he takes office".
Trump has already said that things would be different at the UN after 20 January.
Trump has nominated Indian-American Nikki Haley, Governor of South Carolina, as his Ambassador to the United Nations.
