BERLIN — Julian Assange, the founder of WikiLeaks, promised on Tuesday to release “significant material” over the next 10 weeks about arms, Google, mass surveillance, oil, the United States election and war.

Speaking via a video link at a news conference in Berlin to mark a decade since the inception of WikiLeaks, Mr. Assange vowed that his organization would continue to provide a platform for the release of classified documents held by the United States and by other governments and institutions in positions of global power.

“We hope to be publishing every week for the next 10 weeks, we have on schedule, and it’s a very hard schedule, all the U.S. election-related documents to come out before Nov. 8,” said Mr. Assange, who made his announcement from the Ecuadorean Embassy in London, where he has been living since 2012. “Our upcoming series includes significant material on war, arms, oil, Google, the U.S. elections and myself.”
