Quite a 'dramatic turn of events', considering several 1st hand sources - including people that almost went there to participate in that funeral - remain insistent: most of those that were killed were high military officials of the Houthi/Saleh coalition.

But then, I think that's the very essence of the problem, i.e. the very reason for most of such attacks with 'massive collateral damage' flown by the Saudi-led coalition in this war so far.

'Somebody there' provides 'reliable intelligence' on presence of some Houthi (or Saleh) minister, or top officer, or whatever else. The 'somebody there' must not even be a fan of Hadi (quite on the contrary: most of them tend to ask, 'What Hadi should be our president? Oh, that Hadi? Why him?!?') - nor even an outspoken opponent of Houthis (most of these are languishing in different jails meanwhile, anyway).

All the character in question needs to have is some sort of 'open score' with somebody else who might be present 'there' at the given point in time, or not at all. And a cell phone.

And if some over-eager officer on duty back in the HQ in Riyad happens not to cross-check the backgrounds of the source in question... 'boom'.

Here a short (and much softened) summary of 'Houthi' anti-shipping ops along the coast of the Red Sea: To Threaten Ships, the Houthis Improvised a Missile Strike#Force - with observation that the detail on 'Iranian-backed' was inserted by the editor:

At 7:00 in the evening local time on Oct. 9, 2016, a missile fired from Houthi-controlled territory around the port of Hodeida — on the Red Sea coast in northwestern Yemen — crashed into the water several miles away from U.S. Navy guided-missile destroyer USS Mason, underway in international waters near the Bab Al Mandab Strait.

Mason and the destroyer USS Nitze were escorting Ponce, an amphibious assault ship that supports minesweeping helicopters. Another missile struck the sea in the same area around an hour later.

Mason launched two SM-2 surface-to-air missiles and a single Evolved Sea Sparrow in self-defense — and also deployed a Nulka decoy. It’s unclear whether any of countermeasures were effective. It’s possible the missiles crashed into the sea on their own. The Navy said it would investigate.

But the more important question is where the Houthis — an Iranian-backed Shia rebel movement that controls much of Yemen — got anti-ship missiles in the first place.
