A Belgian mother who biked for charities all over the world had to have both her legs amputated after they were severely mangled in Tuesday’s terror attack in lower Manhattan.

Marion Van Reeth, 54, was one of twelve people hospitalized following the attack, along with her husband and 16-year-old-son, who both suffered neck and head injuries.

She was initially listed as having “massive trauma to both legs,” but a Belgian government official in New York, who insisted on anonymity, confirmed the worst case scenario, adding that the family has given strict instructions that they wished to be left in private.

Van Reeth is a marketing communications manager for Brussels Airlines, according to their website, and was part of the company-sponsored charitable program “Bike for Africa,” which took her on long expeditions through Rwanda, Burundi, Uganda, Senegal and Gambia.

The family lives in Antwerp, where husband, Aristide Melissas, 47, works as an executive for a plastics company his family founded in 1948.

The list of seriously injured also includes Martin Marro, 48, a Boston resident and Argentina native who lost five friends in the attack. Other Argentinians who survived the attack visited Marro in the hospital late Thursday to tell him for the first time that his friends had been killed.

Among those shaken up but not seriously hurt was Noah Salz, a 17-year-old, who was on the school bus hit by the attacker’s rented Home Depot truck.

“I heard a loud crash sound and the bus matron landed right on me,” the teen told WABC.

“I started to cry and then I said, ‘I just want to get out of here as quickly as I can.’ Then I sat there for a minute and heard a gunshot, and I heard it and it was really loud.”

Salz was taken to New York-Presbyterian Hospital with minor injuries—but insisted on going to school the next day so he wouldn’t ruin his perfect attendance.
