Donald Trump on Wednesday hit back at Barack Obama for terming him unfit for presidency, saying the 'terrible president' was a 'disaster' and probably the worst in American history.

Trump's reaction came after Obama said at a White House news conference with the Prime Minister of Singapore "The Republican nominee is unfit to serve as president. He keeps on proving it."

He also directly accused Democrat Hillary Clinton of keeping quiet and not holding a press conference for 241 days questioning her if she is afraid of something.

"There is no doubt in my mind that Donald Trump is unqualified to be president and unfit to be commander-in-chief," Clinton, 68, said. "Anyone who spends his time insulting our military, demeaning the service of our POWs and our fallen soldiers, insulting Gold Star families, this is not someone who understands the honour, the duty of serving America," Hillary said at an event in Colorado yesterday.
