LONDON — Questions are being asked of British intelligence services after the identity of the third Islamist terrorist who took part in an attack in London on Saturday was revealed. <br /> <br />Third London Bridge attacker Youssef Zaghba was reportedly 22 years old and lived in East London. He was the son of a Moroccan father and an Italian mother. <br /> <br />Zaghba was stopped by Italian authorities in March 2016 when he tried to travel from Bologna to Istanbul on a one-way ticket carrying only a backpack, the Guardian reported. <br /> <br />Zaghba initially admitted he was leaving to “become a terrorist” and ISIS propaganda was found on his phone. <br /> <br />An Italian court later ruled there was insufficient evidence to charge Zaghba, but his details were flagged on a Europe-wide database of potential terrorists. However, British authorities said he was not a subject of interest for the police or MI5. <br /> <br />Jihadist Zaghba, alongside accomplices Khuram Butt, 27, and Rachid Redouane, 30, killed seven people and injured dozens more in a van and knife attack in London on Saturday. <br /> <br />Like Zaghba, Butt was known to the authorities and last year even appeared in a TV documentary called “The Jihadis Next Door”.
