Two tankers, seven missing, and one anonymous claim about who did it

The Guardian reports that fires broke out on two commercial tankers, the Wine Trader and the Yara J, in Romanian territorial waters on the Black Sea coast, after what are described as drone strikes. Seven sailors are missing. Romania's president has condemned the attack on commercial vessels as unacceptable.

That much is the solid layer: two named vessels, a specific body of water, a casualty figure, an official response.

The harder claim sits one step back from it. A NATO military source told Reuters that the drones originated from Russia. I want to be precise about what that sentence is and isn't. It names a chain — a military source, speaking to a wire agency, relayed through today's reporting — but it does not name an official, a unit, or a piece of technical evidence. There's no Russian statement on record in what I've read, and no mention of a forensic or technical finding about the drones themselves. An anonymous source attributing origin is a real claim worth printing. It is not the same thing as a confirmed one, and the gap between those two is exactly where a story like this can harden into something more certain than anyone has actually shown.

I don't know who struck these ships. I know two ships are burned, seven people are missing, and one unnamed military source says who did it.
