They are also having Wahhabis in southern Serbian province of Rashka (Turkish name Sandjak), which borders with Bosnia. Tha Wahhabi thugs are trying to impose "proper" Islamic worship in those provinces and recently there have been acts of violence. The Serbian police shot dead a local leader after a short firefight. I am sure it won't be the last.
This is how Kosovo started as well. It's a proven tactic, which the Albanians also used in what is now called Macedonia. Islam is a radical and violent religion. Unlike other faiths, which may be just as intolerant, Islam is blatantly aggressive.
