Republican presidential candidate Donald Trump has attacked his Democratic rival Hillary Clinton, saying Islamic State (Isis) is praying she becomes president and claiming a victory for the former Secretary of State in November would allow the terror group to take over the United States.

Speaking on 12 October at a rally in Ocala, Florida, a key swing state, Trump said he would act as a bulwark against Isis, attacking Clinton's ability to do the same. He said he would "keep radical Islamic terrorists the hell out of our country," according to the Guardian.

"[Isis will] not only take over that part of the world, they'll take over this country, they'll take over this part of the world," he added.

As the Trump campaign becomes paralysed by an onslaught of accusations against the candidate alleging unwanted sexual advances, the property mogul has also attacked Clinton over leaked emails stored on a private email account.

"This is crime at the highest level. She shouldn't be allowed to run for president," Trump said, repeating promises he made during a second televised debate that he would put Clinton in jail over the emails which have been dumped online by WikiLeaks.

"Hillary Clinton bleached and deleted 33,000 emails after a congressional subpoena. So, she gets a subpoena and after – not before, that would be bad – but after getting a subpoena to give over your emails and lots of other things, she deleted the emails. She has to go to jail."

The Clinton campaign has accused Russia of being behind the leaked emails. "It is now clear that the illegal hack of my personal email account was – just like the other recent, election-related hacks – the work of the Russian government," said Clinton campaign chairman John Podesta, the target of the hack.

"This level of meddling by a foreign power can only be aimed at boosting Donald Trump and should send chills down the spine of all Americans, regardless of political party," he added.
