LONDON • British police have named the three men who carried out the terror attack in London on Saturday and who were all shot dead by police. Here is what is known about the trio so far.
KHURAM SHAZAD BUTT, 27
Khuram Shazad Butt was a British citizen born in Pakistan who appeared in a television documentary last year about extremists in Britain. He was investigated by police and Britain's domestic spy agency MI5, but police said there was "no intelligence to suggest that this attack was being planned", Reuters reported.
The Guardian said Butt was a supporter of the banned Islamist group Al-Muhajiroun, which last month urged people in east London not to vote in the British general election.
Butt reportedly went by the name Abu Zaitun, but was commonly known by his nickname Abs.
Neighbours in his east London neighbourhood of Barking said he spoke with a heavy London accent. He was said to be an Arsenal fan and was seen wearing the team's jersey during the attack. Residents of the Elizabeth Fry Apartments in Kings Road said Butt lived in the building with his wife and two children - a boy and a baby girl.
RACHID REDOUANE, 30
Rachid Redouane had "claimed to be Moroccan and Libyan", the authorities said. He sometimes used the pseudonym Rachid Elkhdar. Ireland's national broadcaster RTE said Redouane had an Irish residency card and lived in Dublin as recently as three months ago. The Guardian said he was a pastry chef who had lived in Dagenham in east London, not far from where Butt was residing.
It said Redouane had married a British woman, a London-born care worker named Charisse O'Leary, in Ireland in 2012, and the couple had an 18-month-old daughter. Ms O'Leary never converted to Islam, and the couple recently broke up, said a woman who knew them.
YOUSSEF ZAGHBA, 22
The third attacker named by police is an Italian-Moroccan arrested last year on suspicion of trying to reach Syria, according to Italian media reports. Italy's main media outlets said Youssef Zaghba had an Italian mother from Bologna and a Moroccan father.
The couple were separated and their son, who had passports from both countries, lived mainly in Morocco with regular periods spent working in Britain.
The Italian reports said Zaghba was intercepted at the Bologna airport last year as he was about to board a plane for Turkey, apparently with the intention of joining the Islamic State in Iraq and Syria militants in Syria.
