The Westminster attacker's mother has said she is "deeply shocked, saddened and numbed" by his actions.

Janet Ajao, whose son Khalid Masood killed four people last Wednesday, said in a statement: "I do not condone his actions nor support the beliefs he held that led to him committing this atrocity."

American tourist Kurt Cochran, 43-year-old Aysha Frade and retired window cleaner Leslie Rhodes were killed as Masood drove a rented Hyundai i40 across Westminster Bridge.

The 52-year-old was shot dead by armed police after fatally knifing Pc Keith Palmer in the Palace of Westminster's cobbled forecourt.

Two men arrested in connection with the investigation remain in custody.

Masood's mother said she had "shed many tears" for the people caught up in the "horrendous" attack.
