Extremists elements already spread into many parts of Europe 

It is partly why Erdoğan used this as a bargaining chip against Sweden and Finland from getting Nato membership 

Strangely the West and Nato is not doing much to fight extremists, but focus so much against Russia and China 

So who are these extremists and who are their hidden sponsors

Based on latest reports, it seems like it is more an act of a mentally unstable person rather than a terrorist.
