Also:
Radio shortly before Vettel blocking Alonso.
While the pitcrew did tell him that Alonso was coming some time in advance, they also said that everything behind him was clear and right before the incident, the engineer literally goes "everyone behind you slow".
Might be miscommunication, the engineer lists the driver's behind Vettel and ends with "Alonso 2" as in "Alonso two (seconds behind)" and Vettel might have taken that as "Alonso, too, (behind you)".
The decision of the stewarts should be announced soon. Apparently, Bottas was called in, too, for slowing down in front of Vettel.
Edit:
Yep, it's official, Vettel got a 3 place grid penalty for impeding Alonso.
“The Stewards heard from the driver of Car 5 (Sebastian Vettel), the driver of car 14 (Fernando Alonso) and team representatives and reviewed video evidence.
“ALO was on his fast lap just before the end of Q2. When he approached the last two corners (9 and 10), there was still a queue of 3 cars preparing for their final qualifying lap. VET was the last car in this line and impeded ALO and as a result, ALO had to abort his final qualifying lap.”
Valtteri Bottas and Carlos Sainz were also investigated by the Stewards for ‘driving unnecessarily slowly in the entry of turn 9 and turn 10’ at the same time, however no further action was decided for both incidents.

Pretty nice, you pass a car, slow down, the car behind you impedes someone else, who has to throw away his lap and the sandwiched guy takes the blame. The AM engineers messed up when they didn't tell Vettel about Alonso and Vettel was in Alonso's way, but to see the others get off scott free is just pure bollocks. Second time this season Vettel gets a penalty after being jumped during an outlap and then someone else making a mistake with him being in the wrong place at the wrong time.
Edit2:
I'm legit pissing boiling blood of rage.
Fuck this. Just read that mid paragraph. Fuck FIA.
Apparently, the report for Vettel mentions that he was overtaken by a couple cars who slowed down in front of him, which caused the situation, but do we want to penalise Mercedes for being at least partially at fault by doing something the FUCKING race director himself said was a no-go? Nah, that would make Toto cry bitter tears and we can't have that.
Just check out all those zero other drivers blocking Bottas! Nothing the poor lad could do but slow down to a crawl, blocking everyone behind him.
