The charges came a day after Ullah allegedly detonated a pipe bomb strapped to his body in an underground passageway connecting the Times Square subway station and the Port Authority bus terminal.

The explosion did not kill anyone, but badly injured Ullah and slightly wounded three others.

Ullah said that he carried out the attack in retaliation for U.S. airstrikes on Islamic State in Iraq and Syria (ISIS) militants, and chose the location in New York because of Christmas-themed posters there.

Ullah came to the U.S. from his native Bangladesh in 2011 on a visa for relatives of American citizens, and the White House and Justice Department have called for immigration reforms in the wake of the attack.

John Miller, NYPD's deputy commissioner for counterterrorism and intelligence, said on CBS's "This Morning" on Tuesday that Ullah was not on law enforcement's radar before the Monday attack.

Federal charges are also expected to be filed against Ullah, according to The Associated Press.
