London: A mother on her way to collect her two daughters from school, an American tourist celebrating a wedding anniversary and a respected police officer have all been identified as the victims killed in Wednesday's terror attack in Westminster.
Aysha Frade, 43, was one of two people killed on Westminster Bridge when the attacker, identified by police as British national Khalid Masood, mounted the pavement and mowed down pedestrians, including tourists and locals.

London shaken but defiant after terror attack
Despite a deadly attack in the heart of Britain's capital, life must go on for defiant Londoners who refuse to be "cowed by terrorism".
Mrs Frade was en route to meet her daughters, 8 and 11, when she was hit by the attacker's Hyundai then died under a bus.
Her family is from Galicia in north-west Spain but she was born in the UK, and was married to a Portuguese man.
She worked in administration at the DLD sixth-form college in London. Principal Rachel Borland said staff were "deeply shocked and saddened" by her death.
"All our thoughts and our deepest sympathies are with her family," she said. "We will be offering every support we can to them as they try to come to terms with their devastating loss.
"Aysha … was highly regarded and loved by our students and by her colleagues. She will be deeply missed by all of us."
American tourist Kurt Cochran, 54, and his wife Melissa had been travelling in Europe to celebrate their 25th wedding anniversary and had been due to return to the United States on Thursday. Cochrane was also killed on the Westminster Bridge.
Shantell Payne, a relative, wrote on Facebook "With a heavy heart I must pass the sad news of our beautiful brother, father, husband, son and friend Kurt Cochran, he could not overcome the injuries he received in the London terror attacks.
"This pain is so heart wrenching and raw it has rocked our family and all that knew him to its core. We will miss Kurt beyond words. We love you Kurt. RIP."
She also reported that Melissa was in hospital with a broken leg, rib and a cut on her head "but will recover from her injuries". A GoFundMe page that aims to raise money to help Melissa Cochran while she's unable to work has collected more than $US15,000 toward its $US50,000 goal.
The police officer who was stabbed by Masood and subsequently died of his injuries, Keith Palmer, would be remembered as a "wonderful dad and husband and a loving son, brother and uncle", his family said in a statement released on Thursday afternoon.
He was "dedicated to his job and proud to be a police officer, brave and courageous. A friend to everyone who knew him.
"He will be deeply missed. We love him so much. His friends and family are shocked and devastated by his loss."
PC Palmer was 48 and joined the Met police in November 2001. He was married with a five year-old daughter.
Before joining the parliamentary protection command, he had worked with the Territorial Support Group, a mobile unit specialising in public order (such as riots and sieges) and he had patrolled and worked across London.
James Cleverly, who served with PC Palmer in the Royal Artillery 25 years ago, asked the prime minister in the Commons to formally honour his sacrifice.
"He was a strong, professional public servant and it was a delight to meet him here again only a few months after being elected," Mr Cleverly said, fighting back tears.
"Would my Right Honourable Friend the Prime Minister, in recognition of the work that he did and the other police officers and public servants here in the House do, consider recognising his gallantry and sacrifice formally with a posthumous recognition?"
The Met police said that as a mark of respect PC Palmer's shoulder number - 4157U - would be retired and not reissued to any other officer.
PC James Aitkenhead, who worked alongside PC Palmer in the Territorial Support Group, told the BBC he "knew it would be him" when he learned of the attack.
"That's just the sort of guy he was, to step straight in when others might step back," he said.
US President Donald Trump acknowledged the death of Mr Cochran on Twitter on Thursday, calling him a "great American" and offering his condolences.
A great American, Kurt Cochran, was killed in the London terror attack. My prayers and condolences are with his family and friends.
