Donald Trump has said UN ambassador Nikki Haley will leave his administration "at the end of the year".

Nikki Haley, the U.S. ambassador to the United Nations, said on Sunday that any woman who has felt violated or mistreated by a man has every right to speak up, even if she is accusing President Donald Trump.

The United States absolutely supports a two-state solution to the Israeli-Palestinian conflict and anyone who thinks it does not is in "error", according to US ambassador Nikki Haley.
