London Attack Leaves Citizens of 10 Nations Dead or Injured

One was a police constable with 15 years in the Metropolitan Police force. Another was a British teacher who, according to reports, was walking from her school when she was mowed down by a sport utility vehicle on Westminster Bridge in London. The third was a man from Utah who was on vacation with his wife, celebrating their 25th anniversary.

They were among the victims of an assailant who plowed through pedestrians on the bridge, crashed his vehicle into a fence and then emerged with knives, killing three and injuring at least 40 others in the heart of the city.

Among the wounded, many of them foreign tourists, were 12 Britons, four South Koreans, three French high school students, two Romanians, two Greeks and one citizen each of China, Germany, Ireland, Italy and the United States.

The suspect was fatally shot by the police, but the attack, called a “terrorist incident” by the authorities, threw the seat of Britain’s government into turmoil and put ministers under lockdown for hours.

On Thursday afternoon local time, the police identified the assailant as Khalid Masood, 52. Prime Minister Theresa May said in Parliament that the suspect was British-born and was previously investigated by MI5, Britain’s domestic counterintelligence agency, for possible ties to violent extremism.
