Special forces from the West are on the ground in Ukraine, according to classified documents leaked online. The largest contingent is from Britain (50), followed by NATO members Latvia (17), France (15) and the US (14).
It is unclear what the special forces are exactly doing, where they are or whether their numbers have consistently been at this level.
However, the revelation confirms what many have speculated since the war began February last year. A trove of US documents marked "top secret" have been leaked and posted online recently, outlining compromising details about the war in Ukraine and its Western allies.
They have not been verified. Yet, US officials have scrambled to have them purged from social media, as they investigate the source of the disclosure.
