WikiLeaks has activated "contingency plans" after its founder lost Internet access.
The alleged move by the Ecuadorian Embassy comes as the anti-secrecy organization ramps up its campaign on Hillary Clinton.
WikiLeaks on Monday said the Ecuadorian Embassy in London had cut Internet access for Julian Assange, the whistle-blowing organization's founder and editor-in-chief.
"We can confirm Ecuador cut off Assange's Internet access Saturday, 5 p.m. GMT, shortly after publication of [Hillary] Clinton's Goldman Sachs speeches," the organization noted on social platform Twitter, AFP reported.
"We have activated the appropriate contingency plans," WikiLeaks said in an earlier tweet.
A spokesperson for the organization, speaking with AFP, claimed the cutoff was directly linked to WikiLeaks' ongoing publications concerning US Democratic presidential candidate, Hillary Clinton.
Days before the Democratic National Convention in July, WikiLeaks published damning internal emails that revealed a concerted effort to undermine the presidential campaign of Clinton's competitor, Senator Bernie Sanders.
Democratic Party officials and the Clinton campaign have accused Russia of involvement in a series of hacks on the American political party's servers, including "senior-most officials".
