Where did this 'come out'? Either of these, as you describe them, would have been a major international incident.

Just because it's not talked about at length by the mainstream media, doesn't mean it didn't happen. Take a look at these two videos:
For what it's worth, I'm not aware of any Russians who died in that attack.
It probably helps to think of secrecy under the broader term of information management. If something isn't secret per se, but the information is suppressed so that it doesn't become common knowledge, isn't the outcome broadly the same? I'd argue that's what we're seeing here. That's how the US is getting away with arming Al-Qaeda (or at least former Al-Queda) to fight against ISIS, for example, even though they frequently fight alongside each other. If the US public was more aware of this then there's be greater pressure to stop, but that pressure is virtually non-existent due to the complicity of the mainstream media, helping to keep it away from public debate.
Also Israeli media reported this.
