Person above you either didn’t read the article they posted or is hoping other people won’t. Not that Al Jazeera doesn’t have its own biases and blind spots like any news source, but I don’t see anything incorrect in that article. They even put quotes around the word attack and then say only that Houthis claim they attacked them. It only mentions a sunk ship when it talks about the Houthi attacks on merchant vessels, which is true, they they sunk a Belize flagged ship containing fertilizer and fuel that was on its way from the UAE to Bulgaria.

It would not. It’s a defensive treaty.

Ukraine isn’t a part of France or under the jurisdiction of France, so the attack wouldn’t be on France’s territory, and Ukraine isn’t a member of NATO itself.
