The UN Chief has cautioned Donald Trump against abandoning the idea of a two-state solution to the Israeli-Palestinian conflict, saying there is no alternative. It comes after Mr Trump went against decades of US policy, saying he would back whatever formula led to peace. <br/><br/>Palestinians reacted with alarm to the possibility that the US could drop support for Palestinian statehood. The last round of Israeli-Palestinian peace talks broke down in 2014. Speaking alongside Israeli Prime Minister Benjamin Netanyahu yesterday, President Trump promised to deliver a great peace deal. But he said both sides must compromise.
