This doesn't seem to have gotten much traction in the MSM yet, but could be of increasing concern going forward. From the AP yesterday:
The sinking of the Tutor marks what appears to be a new escalation by the Iranian-backed Houthis in their campaign of attacks on ships in the vital maritime corridor over the Israel-Hamas war in the Gaza Strip.
The attack comes despite a monthslong U.S.-led campaign in the region that has seen the Navy face its most-intense maritime fighting since World War II, with near-daily attacks targeting commercial vessels and warship.
The Liberian-flagged, Greek-owned-and-operated Tutor sank in the Red Sea, the British military's United Kingdom Maritime Trade Operations center said in a warning to sailors in the region.
…
The use of a boat loaded with explosives raised the specter of the attack in 2000 on the USS Cole, a suicide assault by al-Qaida when the warship was at port in the Yemeni city of Aden, killing 17 on board. The Cole is now part of a U.S. Navy operation in the Red Sea led by the aircraft carrier USS Dwight D. Eisenhower to try and halt the Houthi attacks, though the rebels continue their assault
Interesting, and more than a bit ironic, that the USS Cole is now part of the Red Sea mission to deter Houthi attacks on international shipping.
IIRC, the Houthis have made all sorts of absurd claims about the effectiveness of their attacks on shipping in the Red Sea (including the sinking of the Eisenhower itself!), but unfortunately this one was all too real -- including the death of a Filipino sailor on board the Tutor when it was first hit last week.

OK -- Update keeps deleting my update for some reason, so I'll try this as an edit. It seems the MSM is starting to cover this after all, with reports now from Reuters, CBS, and the BBC (among others).
What's worse, it seems there was yet another attack on a different ship the day after the attack on the Tutor last Wednesday. From the BBC:
A Palauan-flagged, Ukrainian-owned bulk cargo carrier en route to Italy, the Verbena, was also seriously damaged when it was struck by two anti-ship cruise missiles fired from Houthi-controlled Yemen while sailing in the Gulf of Aden last Thursday.
...
On Saturday, the Verbena’s remaining crew issued a distress call saying they were abandoning ship because they were unable to bring the fires under control.
They were rescued by another cargo ship which was in the area and transported to safety. Central Command said an Iranian warship in the vicinity "did not respond to the distress call".
