As someone from Europe who isn't French. It's just another France rioting story. It might be big in France but for the rest of us, it's just looks like another France rioting story which they were doing for the past few months.
It's not just that it's barely registering on Twitter, it's barely registering anywhere because lots of us are just so used to France rioting that it's not really news. It's like mass shootings in the US. I think there was a new one over 4th July holiday period but I am not 100% sure because we're so numb to mass shootings out of the US. They need to do something super wtf like have the police stand outside a classroom while a school shooter is shooting children for us to register.
