The leak of highly classified US documents is a "very serious" security risk, the Pentagon's top spokesman said on Monday.
Ednews informs via Euronews that Washington is taking steps to mitigate the damage from the disclosure, which revealed sensitive information about the conflict in Ukraine, such as the situation on the front and Kyiv's crucial anti-aircraft defences.
"We don't know who is responsible," said National Security Council spokesman John Kirby. "We don't know if they have more [documents] to post. Is this a concern for us? Absolutely."
The damaging leak has raised eyebrows among the US allies.
Intelligence involving other nations was revealed, with some documents mentioning that Israel's secret service Mossad would defend demonstrations inside the country against controversial judicial reform.
