Travel to USA from UK

[ukraj]

I would be travelling to USA(ORD) from United Kingdom(BHX) through Paris(CDG) with Air France.
I am currently in the UK on a 1 year work permit. I would be travelling to the USA on a B1/B2 visa.
My Nationality is Indian.
I do not intend to leave the Charles de Gaulle airport.
Would I be needing any Transit Visa at the Paris airport?

Similarly I would be returning from USA(ORD) to United Kingdom(BHX) through Amsterdam(AMS) with KLM.
I do not intend to leave the Amsterdam Airport.
Would I be needing a Transit Visa at the Amsterdam Airport?
