But the explosion sowed panic and disrupted the morning commute during the busy Christmas tourism season, six weeks after another a truck driver, also reportedly inspired by the IS group, killed eight people on a bike path.
Ullah, a driver, was convicted on all six counts and faces a maximum sentence of life behind bars when he is sentenced on April 5, 2019.
His convictions include supporting a foreign terrorist organization, using a weapon of mass destruction and bombing a public place.

He was caught on CCTV walking through the subway terminal and detonating the bomb strapped to his body. After his arrest, he allegedly told authorities: “I did it for the Islamic State.”
“Today, Ullah stands convicted, he faces a potential life sentence, and his purpose failed. New York City remains a shining symbol of freedom and hope,” said Geoffrey Berman, the top US federal prosecutor in Manhattan.
Ullah built the bomb in his apartment, packing the device with metal screws and Christmas tree lights, having planned the attack for several weeks.
