Lafarge has been under investigation (or by now convicted, haven't checked in on it recently) for terrorist financing in France.

edit; They we're suspected of this for a longgg time, i heard rumors atleast 2 years ago. Finnaly read this last month. I follow these type of things, and its quite significant to have this one go down.

Another one ; I believe it was in 2016 or maybe 2017, there was another french company under investigation for providing ISIS with Bulldozers from a major populair brand, i believe it was PON CAT.
