Trump: Clinton's foreign policy plan would start WW3
Republican presidential candidate Donald Trump has said his rival Hillary Clinton's foreign policy plan in Syria would trigger World War Three.
He also said the US should focus on defeating so-called Islamic State (IS) rather than removing Syria's president.
Mrs Clinton has proposed a no-fly zone over Syria. The top US military chief has said that could spell conflict with Russian jets in the region.
The Clinton campaign accused Mr Trump of "playing to Americans' fears".
Mr Trump also attacked Republicans for not uniting behind his candidacy.
"If we had party unity, we couldn't lose this election to Hillary Clinton," he told Reuters news agency at Trump National Doral golf resort in Miami, Florida.
