Westminster attack: 75-year-old dies as thousands honour victims

A 75-year-old man injured in the attack on Westminster Bridge has died of his wounds on Thursday night as thousands gathered in the city centre for a candlelit vigil for the victims.

In a statement late Thursday, London’s Metropolitan Police say said life support was withdrawn from the man and his family has been notified.

The announcement brings the number of victims killed in Wednesday’s attack to four.

The attacker, who rammed his car into pedestrians on Westminster was also killed by police after he jumped out and stabbed a police officer to death.

Meanwhile, several thousand people gathered in London's Trafalgar Square on Thursday evening for a candlelit vigil to honour the victims and their families and to show London's unity in the face of militant attacks.

Dignitaries, police and clergy from various faiths gathered on the steps leading to the National Gallery.

There was a strong sense of solidarity and camaraderie, with Muslims mingling with Jews and people stopping to thank the police for their work.

After speeches and a minute's silence - the crowd was so quiet that Big Ben could be heard chiming in the distance - the home secretary, mayor and acting police commissioner lit the three oversize candles to applause from the crowd

Sughra Ahmed, a Muslim woman who traveled from northwest England for the vigil, said she had been reduced to tears on the square by a woman who went out of her way to embrace her.

"Britain is one," she said. "An attack on one is an attack on us all."
