FOX News reports that a man suspected of bombing a transit terminal has been indicted by a grand jury on terrorism and explosives charges.

Akayed Ullah, 27, has been indicted on six counts, including attempting to use a weapon of mass destruction and attempting to provide support to the Islamic State, according to the U.S. Attorney Office.

Ullah allegedly detonated a bomb in a transit hub in New York City in December. He set off a pipe bomb inside the Port Authority subway terminal on the 11th of December, 2017, just as the morning rush hour was taking place. Ullah as well as four victims were injured, though Ullah suffered the worst injuries – abdominal wounds, injuries to his hands and burns.

The suspect was taken to the hospital for treatment of his injuries, but did not immediately give a clear motive for the bombing. He did tell law enforcement at one point that he was trying to "avenge U.S. aggression against the Islamic State group," according to the AP.

His original charges included criminal possession of a weapon, support of an act of terrorism and making terrorist threats, according to the NYPD.

According to authorities, he was inspired by ISIS to carry out the bombing. Considered “an attempted terrorist attack” by the New York Mayor, Bill de Blasio, the city is happy he did not inflict as much damage as was originally hoped for.

Ullah is from Bangladesh and is in the country on a chain migration visa, says the Department of Homeland Security Press Secretary, Tyler Houlton. He entered the U.S. in 2011 with a family immigrant visa, and was here as a legal permanent resident.
