New York City Mayor Bill de Blasio says there are no known additional threats to the city following Monday morning's attempted bombing in a subway corridor.
"When we hear of an attack on the subway, it's incredibly unsettling," de Blasio said in a news conference following the incident. "And let's be also clear: this was an attempted terrorist attack."
The mayor says officials are grateful the situation wasn't more severe.
"Let me just say it’s very important for my fellow New Yorkers to know there are no additional [threats] at this point," he said. "All we know of at this time was one individual who, thank god, was unsuccessful.”
Four people were injured in the explosion, including the suspect, a male who suffered burns and lacerations.
The suspect has been identified as Akayed Ullah, 27, an immigrant from Bangladesh who has an address in Brooklyn. He was reportedly conscious when he arrived at the hospital and made statements to police.
Law enforcement officials say Ullah attached a "low tech" pipe bomb-like device to his body with velcro and zip ties. The device exploded in a corridor, between subway platforms at about 7:20 a.m. Monday.
The incident was captured on surveillance video in the tunnel.
The three victims reportedly suffered minor injuries like ringing in their ears, evacuated the scene on their own power and checked themselves in to local hospitals.
Commuters are urged to call 888 - NYC - SAFE if they notice anything concerning or out-of-the-ordinary on mass transit.
