The ringleader of the Paris terrorist attacks claimed he entered France among a multinational group of 90 jihadis who remain scattered throughout the area, it has emerged.

Abdelhamid Abaaoud told a friend of his cousin in the days following the attacks that it was easy for ISIS terrorists of all nationalities, including the British, to flood into Europe by mingling with migrants.

Posing as a Romanian vagrant, the 28-year-old Belgian also boasted of murdering 130 people 'like he'd just been shopping,' the woman revealed.

His behavior after the carnage on November 13th will be of huge concern to those allowing thousands of foreign down-and-outs, including many Roma gypsies, into the French capital.

Referring to the rows of people killed standing or sitting outside cafés, Abaaoud told the woman - who later notified police that he was living in the suburb of St Denis - 'the terraces – that was me'.

Sonia said: 'He had a bobble hat on his head, orange trainers and a bomber jacket. For me he was a Romanian. Also, he was smiling, he did not look like a terrorist.

'He spoke about the attacks as if he had been shopping and had found a box of discounted washing up liquid. He was happy. That was it.'

Sonia met Abaaoud two days after the attacks, on an industrial estate in Aubervilliers, a northern suburb of Paris where communities of Roma travellers from Romania set up shanty towns.

Abaaoud was initially undisturbed as he slept on a mattress under a bush, but Sonia was determined to bring him to justice.

She arrived with his cousin - another young woman called Hasna Ait Boulahcen - and the pair texted him the code number '1010' before Abaaoud greeted them.

Abaaoud said around 90 jihadists of all nationalities - including some from Britian - had returned from Syria using false papers and were ready to spread further carnage.

Abaooud, who is said to have visited London and Birmingham in the months leading up to the attack in France, also boasted he was preparing more on a police station and a nursey in La Defense, the business district to the west of Paris.

'He told me they were going to do it on Thursday and I said to myself I have to stop them,' said Sonia.

She dialled the emergency number set up by the Ministry of Interior in the aftermath of the attacks, and told security agents that Abaaoud had moved to a flat in the suburb of St-Denis, along with Hasna Ait Boulahcen.

On November 18, police raided the flat killing Abaaoud, Hasna Ait Boulahcen and Chakib Akroh, another ISIS operative who had taken part in the terrace attacks alongside Abaaoud.

Sonia has since gone into hiding, and changed her identify, but agreed to speak on RMC radio in Paris today.

She said she felt abandoned by France - the country she risked her life defending, but added: 'Even if I live in danger, really, I'd rather it this way than have the death of innocent people on my conscience'.
