A video showing Muslims in London stepping in to stop extremists from delivering messages in public has been shared thousands of times.
"Hey! Go to Syria and live there," one man shouts in response to Muhammad Shamsuddin, who was holding the flag of a group that advocates for the implementation of Sharia law. Shamsuddin was preaching in London that the flag would one day fly above 10 Downing Street. Radical Islamist preachers trying to spread their message also faced vocal protests on Edgware Road in London.
