Donald Trump has accused Hillary Clinton of "playing chicken" with Russia and suggested her presidency would risk starting a nuclear war.

Speaking about Russian President Vladimir Putin during the third Presidential debate, Mr Trump said: “He has no respect for her. He has no respect for our president."

“And I’ll tell you what she’d in very serious trouble, because we have a country [Russia] with a tremendous numbers of nuclear warheads.

“18,000, by the way, where they [Russia] expanded and we didn’t. 18,000 nuclear warheads and she’s playing chicken.

"Putin, from everything I see, has no respect for this person."

Ms Clinton responded: "That’s because he’d rather have a puppet as the president of the United States. It’s pretty clear." She said Trump was willing to "spout the Putin line".
