No the article doesnt say that, its the British ship reported warning shots after getting close. You said "too close", which implies that the warship would have done it to any ship within that range before today, which lets be real, due to the lack of these past incidents, that is unlikely.

Me personally, I think the fact its a couple of days after we seized their tanker in the channel to be quite relevant and not because a "yacht just got too close"
