WASHINGTON, April 10. /TASS/. The US Department of Defense (DoD) will assess the validity of classified documents posted last week on social networks, Pentagon deputy press secretary Sabrina Singh said in a statement on Monday.
"An interagency effort has been stood up, focused on assessing the impact these photographed documents could have on US national security and on our Allies and partners," she said.
"Over the weekend, US officials have engaged with Allies and partners and have informed relevant congressional committees of jurisdiction about the disclosure," Singh added.
Last Thursday, the New York Times reported citing representatives of the administration of US President Joe Biden that the Pentagon had launched an investigation into the leak of classified documents regarding US and NATO plans to prepare the Ukrainian armed forces for a counteroffensive against Russian forces.
Numerous documents revealing information about schedules for the supply of weapons, the number of troops and battalions have been published on social networks such as Twitter and Telegram.
The documents contain a timetable for the preparation, acquisition of equipment and ammunition for the spring counteroffensive of nine brigades of the Ukrainian armed forces, which are trained and equipped by the United States and allies.
According to the documents, six of them were supposed to be ready by March 31, three more - by April 30, data on the three brigades of the Ukrainian armed forces, which are being preparing by Kiev itself are not provided.
Mikhail Podolyak, adviser to the head of the office of the President of Ukraine, wrote on his Telegram channel last Friday that the data published on social networks is not true and has nothing to do with Kiev’s real plans.
However, last Friday the New York Times reported again that a new batch of the US classified documents on Ukraine surfaced on social media sites.
According to the daily, American classified documents on the Middle East and China also appeared on social networks, including on Twitter. In total, the publication points out, there were more than 100 documents on the Web. Some of the papers were marked that their content should not be known to representatives of any other country.
One of the intelligence officials described the leak as "a nightmare for the Five Eyes… In a reference to the United States, Britain, Australia, New Zealand and Canada, the so-called Five Eyes nations that broadly share intelligence," the newspaper added.
