One of the leaked Pentagon documents , which appeared online as part of a set of leaks, showed how many NATO special operations forces are inside Ukraine , according to The Guardian.

According to the newspaper: "One of the slides indicated that a small contingent of less than a hundred special operations personnel from NATO members France, America, Britain and Latvia, was actually active in Ukraine."

According to a copy of the document circulated on Twitter, whose authenticity has not been verified, there are 97 NATO special operations soldiers inside Ukraine, including 14 Americans.

On Saturday, the French government denied the presence of its forces inside Ukraine. There are no French forces operating in Ukraine. The documents mentioned do not come from the French armies. "We do not comment on documents of uncertain origin," said a spokesman for the French Armed Forces minister.

Last Thursday, The New York Times first raised the issue of the leaked documents, which appeared online. The documents show the US is planning a Ukrainian counterattack and appear to be authentic as the Biden administration scrambled and the Justice Department launched an investigation into the leak.

A new trove of documents emerged on Friday that extend beyond Ukraine's borders and include reports on China, North Korea, Iran, Israel and other regions around the world. According to the Washington Post, the Pentagon restricted the flow of intelligence in response. A US official said the move "revealed a high level of panic among the Pentagon leadership".

The Washington Post report said the slide, which showed fewer Russian casualties than Ukrainians, appeared to have changed. But there was no indication that other documents, which would include the slide that showed the number of special operations forces in Ukraine, had been amended.

Western media reported earlier about the presence of NATO special operations forces in Ukraine. The Intercept reported last October that there were US special operations forces on the ground, and in June 2022 the New York Times reported that there were a few dozen commandos from Britain, France, Canada and Lithuania.

Earlier in January, an anonymous member of a chat group with just over 10 members posted files containing US military documents classified as "secret" and "top secret."

The Wall Street Journal said, in an extensive report on these military documents, that "it seemed that no one in the outside world had noticed" when the documents were leaked for the first time.

According to the newspaper, the documents - which appear to be in the hundreds - remained until early March among members of the small group on the "Discord" messaging platform, a social networking platform for chatting.

And in early March, another user re-posted dozens of those documents in another group with a larger audience, before it spread among the Minecraft community.

On Wednesday (April 5), a Russian propaganda account on Telegram published a "grossly fake" copy of one of the documents, along with a few other unedited documents, according to the same newspaper.

Officials said the intelligence leak represents one of the most damaging leaks in decades and is seen as one of the most serious security breaches after the 2013 WikiLeaks leaks, which included more than 700,000 documents, videos and diplomatic cables.

US officials said Saturday that the United States is considering a range of possibilities for how the leak occurred, including that someone with a top-secret security clearance leaked information or hacked US intelligence systems.
