Mystery swirls around Assange's status at Ecuadorean Embassy

Midway through releasing a series of damaging disclosures about US presidential contender Hillary Clinton, WikiLeaks founder Julian Assange says his hosts at the Ecuadorean Embassy in London abruptly cut him off from the internet.

The news adds another layer of intrigue to a campaign which has been roiled by dramatic leaks and allegations of state-sponsored subversion.

Citing unidentified "multiple US sources", WikiLeaks said the request was made on the sidelines of negotiations which took place last month in Colombia.
