A mother on her way to collect her children from school has been named as one of the victims of the London terror attack.
Aysha Frade, 43, was named tonight by police as one of the four dead.
She was walking across Westminster Bridge when she is believed to have been struck by the killer's car and thrown under a bus, the Daily Mail reports.
She has been described as "a highly regarded and loved" member of staff at DLD College near Westminster Bridge, the BBC reports.
Ms Frade and three others were killed by the "lone wolf" terrorist later shot dead as he attacked officers at Westminster Palace on Wednesday.

Earlier, the policeman killed in the attack was identified as PC Keith Palmer, 48, a 15-year veteran of the police force.
PC Palmer was a husband and father, it has been reported.
He served in the Royal Artillery before becoming a policeman, MP James Cleverly said.
"I've known Keith for 25 years. We served together in the Royal Artillery before he became a copper," Mr Cleverly tweeted.
"A lovely man, a friend. I'm heartbroken."
