Shaykh Dr Muhammad Umar Al-Qadri says that two mosques are seeing Islamic extremists congregating there regularly
The Imam of the Al-Mustafa mosque in Blanchardstown also claims that there are now up to 100 extremists in Ireland.
He says that his group, the Muslim Peace and Integration Council, is working to promote peace but are meeting resistance in some quarters.
Speaking to the Irish Independent, he said: “We need to stop the radicals from spreading their lies to the youth.”
But he said that in one mosque, the religious leaders never denounce atrocities carried out in the name of the terror group Isil.
