The number of extremists known to the security forces is only "the tip of the iceberg", Birmingham MP Khalid Mahmood has warned.
He called for tougher controls on Islamic schools known as madrassahs, to ensure they are not promoting extremist beliefs, and said teachers of Islam, known as imams, should be subject to security checks.
Mr Mahmood, the Labour MP for Perry Barr, was speaking as MPs debated changing the law to prevent people convicted of terrorism offences being released from jail half-way through their sentence.
It follows a terrorist incident near London Bridge last year in which two people were killed, an an attack in Streatham on February 2. In both cases, the perpetrators had been automatically released from jail part way through serving a sentence.
Mr Mahmood said some violent extremists might consider themselves Muslims but they practiced a "misguided version of Islam". He said: "They do not practise Islam; they practise what they believe is Islam. Islam in itself is a peaceful religion." [Birmingham Mail] Read more
