US President Donald Trump has denied that the planned relocation of the US embassy in Israel to Jerusalem would take place within a year, rejecting comments made a day earlier by Israeli Prime Minister Benjamin Netanyahu.

In an interview with Reuters, President Trump said that he does not think that it would happen so quickly.

The United States officially recognized Jerusalem as Israel's capital in December last year and said America's embassy would move there but did not provide a timeframe.

Secretary of State Rex Tillerson said in December that a three-year timetable was probably optimistic.
