Excerpt from an article from the AP:
Death threats are taken a lot more seriously since the slaying in the Netherlands two weeks ago of Dutch filmmaker Theo van Gogh by a suspected Islamic radical. Van Gogh had produced a brief television movie highly critical of the treatment of women in Muslim families.
This event has caused a domino effect of chaos between Muslims and non-Muslims in Holland and appears to be spreading to nearby countries. There is already the cultural, sometimes language, and religious differences that can divide the groups that usually co-exist around Europe like in Holland, Belgium, Germany, and France. It could have been seen like a bomb waiting to explode and now it appears that it has. Hopefully peace can be returned soon.
