Role of western intelligence under scrutiny, scale of release 'unprecedented'

The United States and its NATO allies have stated publicly that they're providing Ukraine with satellite images, intercepting Russian communications and helping to defend Ukraine from Russian cyber-attacks. But leaks and statements from within the US intelligence community are now claiming even closer involvement - like with the sinking of the Russian missile cruiser Moskva. The ship was struck by Ukrainian missiles, but there are reports the US provided information about its location.

This month the New York Times reported that the US had provided intelligence that helped Ukraine kill several Russian generals on the front lines.
