Belgian police on Wednesday detained 15 members of a radical Islamic group after they harassed passers-by in the city of Antwerp and shouted anti-Western slogans, police said.
The Sharia4Belgium militants distributed leaflets glorifying Islam and criticizing the Western way of life in a central street of the northern port city, Belga news agency quoted a police spokeswoman as saying.
"Organisers had made no request for a demonstration, which was therefore not authorised," said the spokeswoman.
