Kreb cycle substrate-level or oxidative phosphorylation?

I keep seeing mixed answers.
So to clarify, does the Kreb cycle fall under substrate-level phosphorylation or oxidative phosphorylation?
What about Carboxyl decarboxylation? (since you don't produce any ATP)

 

[Msmouth]

Krebs = substrate level
ETC= Oxidative phosphorylation

Not sure about 2nd question....

 

[LaughingGas]

Decarboxylation = None but the NADH will follow the oxidative phosphorylation through ETC.

Thanks everyone!
I had a hunch Kreb was substrate level since you make GTP
