Three Attacks in Three Months – Westminster, Manchester and London Bridge
The three attacks have many common features. All of them were undertaken by Islamist extremists and claimed by Daesh, although the claims are yet to be corroborated.
Khalid Masood’s attack on Westminster was conducted in a manner consistent with declared Daesh activity throughout mainland Europe and in a way promoted by extremist publications, such as Inspire and Rumiyah. Salman Abedi’s travel to Libya was likely for extremist purposes and his family there were known to support extremists, particularly al Qaeda affiliated groups. It is also potentially where he gained the knowledge to build an explosive device. The attack undertaken by Youssef Zaghba, Khuram Butt and Rachid Redouane in London Bridge is also consistent with the methodology promoted by extremist publications and strong links exist between them and al Muhajiroun (ALM). The attackers were known to MI5 and the police, but the degree of interest the authorities had in them is currently unclear.
