Officials in London, Brussels, Berlin, Dubai and Kyiv questioned Washington about how the information ended up online.

Senior U.S. officials are racing to placate frustrated and confused allies from Europe to the Middle East to Kyiv following the leak of highly classified information about the war in Ukraine and other global issues.
After the news of the leak broke last week, senior intelligence, State Department and Pentagon officials reached out to their counterparts to quell worries about the publishing of the intel, according to four officials — an American, two European and one Five Eyes member — familiar with those conversations.
One said that members of the Five Eyes — the intelligence consortium of the United States, Canada, United Kingdom, Australia and New Zealand — have asked for briefings from Washington but have yet to receive a substantive response. Inquiries have been sent separately to the Office of the Director of National Intelligence, Central Intelligence Agency and Federal Bureau of Investigation.
Meanwhile, officials in London, Brussels, Berlin, Dubai and Kyiv questioned Washington about how the information ended up online, who was responsible for the leak and what the U.S. was doing to ensure the information was removed from social media. They also questioned whether the Biden administration was taking steps to limit the distribution of future intelligence. As of Monday morning, U.S. officials had told allies the administration was investigating and that they were still trying to understand the full scope of the leak, the European officials said.
Ukraine has long worried about information it shares with the U.S. spilling out into the open. “This case showed that the Ukrainians have been absolutely right about that,” said one of the European officials, who like others was granted anonymity to speak about the sensitive leak. “Americans now owe the Ukrainians. They have to apologize and compensate.”
The saga has left the U.S. relationship with its allies in a state of crisis, raising questions about how Washington will correct what officials worldwide view as one of the largest public breaches of U.S. intelligence since WikiLeaks dumped millions of sensitive documents online from 2006 to 2021.
The distress over the leak is particularly problematic because the majority of the documents focus on the war in Ukraine — an effort the U.S. has repeatedly said hinges on collaboration among allies in NATO, Europe and elsewhere.
“The manner of the leak and the contents are very unusual,” said a former U.S. intelligence analyst who focused on Russia. “I can’t remember a time when there was this volume of a leak and this broad of a subject matter of authentic information that was just put on social media rather than say, the Snowden files, that went through a group of journalists first.”
The Pentagon, CIA, ODNI, and FBI declined to comment.
More than 100 U.S. intelligence documents were posted on Discord, a secure messaging app, as early as March 2 and contained sensitive, classified information about the war in Ukraine, Russian military activity, China and the Middle East. The photographed papers, which appeared to have been folded over and then smoothed out, contained top secret information, including from the Central Intelligence Agency.
Appear to have been assembled into a briefing packet by the Joint Staff’s intelligence arm, known as J2, with summaries of global matters pulled from various U.S. intelligence systems. Some of the documents contain markings in the corners that correspond with specific wires with information that appear to be compiled in summary form — a practice often used by individuals inside the government to prepare briefing packets, the former U.S. intelligence analyst said.
