Security and intelligence officers are reportedly meeting the Garda Commissioner this morning, after it emerged one of the London attackers lived in Dublin for a time.
An Irish ID card was found on one of the men, after they were shot dead by police.
The man was not known to Gardaí here and did not come to their attention in relation to any crime or security issues. The man is believed to have been of Moroccan origin and the Irish Daily Star report he lived in Rathmines until as recently as one year ago.
In a statement to 98FM News, An Garda Síochána said:
"An Garda Síochána is providing every assistance to our colleagues in the London Metropolitan Police in relation to the terror attack in London. We will process all requests from the UK authorities in relation to enquiries into individuals, identities or any other matter".
Meanwhile in London, a number of people have been detained this morning following Saturday's attacks.
A number of raids took place in Newham and Dagenham. Eleven people arrested over the weekend are still being questioned.
Police say they know the identities of the three men who carried out the van and knife rampage, but won't name them yet.
