Excerpt:
German author and undercover journalist Shams Ul-Haq claims to have visited hundreds of mosques across Germany, Austria, and Switzerland and says that one in ten mosques there preaches radical Islamic ideas.
Mr Ul-Haq, who is originally from Pakistan, said that the number of mosques that preach hatred of the west and adherence to radical Islamic ideas is growing across the German-speaking countries of Europe with at least 50 in Austria alone, Kronen Zeitung reports.
During his visits, Ul-Haq also noticed that the imams were often not the real drivers behind what was preached but were pushed by financial backers who dictate what they said in sermons.
Ul-Haq also met with radical Salafists but said that they did not immediately approach him and were very wary of newcomers.
