Paris knife attacker kills his mum and sister shouting 'Allahu Akbar' as ISIS claims responsibility

A knifeman armed with several blades killed his mum and sister and seriously injured another person in Paris in an attack claimed by ISIS.



The attacker, who was known to intelligence services, was shot dead in the suburb of Trappes after charging at police.



ISIS has claimed responsibility for the bloodbath, describing the killer as an "Islamic state fighter", but has offered no further evidence.



However sources in Paris suggest that the slaughter was the result of a domestic argument.



The 36-year-old taxi driver, named as Kamel Salhi in local media, is said to have attacked his sister in the street before killing his mother inside a home.



Police sources told Le Parisien that the man told police while he was inside the home: "Allahu akbar, if you enter I smoke you all."
