The radical imam Anjem Choudary is sentenced to life imprisonment in the United Kingdom.
Choudary is notorious as one of the country's most violence-promoting preachers, and has been found guilty by a court of leading the banned extremist network al-Muhajiroun.
The extensive police investigation has been carried out in cooperation between the London police, the New York police, and the police in Canada.
Choudary has previously served a prison sentence in the United Kingdom for supporting the terrorist group IS.
