London police have named two of the perpetrators of the June 3 attack - 27-year-old Khuram Shazad Butt and 30-year-old Rashid Redwan.
Khuram Shazad Butt was a native of Pakistan and held British citizenship. He was known to the police and special services, but the authorities had no information about the training.
Rachid Redouin was not on the radar of the police. It is reported that he called himself a native of Morocco and Libya and used the name Rashid Elkhdar and called a different year of birth - 1991 instead of 1986.
Update. On June 6, the London police named the third participant in the attack - this is 22-year-old Yousef Zagba. According to the police, he was a native of Morocco and had Italian citizenship. He did not fall into the field of vision of British law enforcement and intelligence agencies.
