Suspected New York City bus terminal bomber Akayed Ullah has been charged with terror offences.
The 27-year-old Bangladeshi immigrant was wounded in the attack at the Port Authority Bus Terminal in Manhattan on Monday morning.
Mr. Ullah is reported to be in a serious condition in hospital after suffering burns when a crude device that was strapped to his body exploded.
Three other people suffered minor wounds in the blast during rush hour.
The New York Police Department (NYPD) tweeted on Tuesday that Mr Ullah had been charged with criminal possession of a weapon, supporting an act of terrorism and making a “terroristic threat”.
He told police investigators he had been inspired by Christmas terror attacks in Europe and selected the Port Authority bus terminal after seeing a number of festive posters on the subway walls.
Mr. Ullah said the planned attack had been motivated by US air strikes on IS targets in Syria and elsewhere.
Reports say he used piping, nails, a 9-volt battery and Christmas lights wire to build the device. It was affixed to his body with Velcro straps.
The suspect’s home in the New York City borough of Brooklyn is being searched. Police believe he acted alone.
