A member of the Somali community in Cardiff told our reporter Rob Osborne that he is shocked by the claim from al-Shabaab that it has recruited members from Cardiff - as "I have not come across anybody who would have sympathy with a terrorist organisation."
"I haven't heard of anybody being radicalised. In the past there were people who attempted to radicalise our young people in Cardiff, however all their attempts failed."
The man, who wishes to remain anonymous, said young people in the Somali community in Cardiff "see al-Shabaab as a radical, terrorist organisation - and they don't want to have anything to do with it".
"We are working hard to give our young people the right information about their religion, so anybody who comes to them with these radical views about harming themselves and harming other people - they will simply reject."
"I am very surprised. Whoever says that Cardiff is one of the cities in the UK that might have some sort of link with al-Shabaab... that is baseless."
