The New York City Police Department confirmed Monday that an explosion at the Port Authority in New York was a "terror-related incident."

The explosion, around 7:20 a.m. ET by 42nd Street and 8th Avenue near Times Square, forced officials to evacuate the A, C and E subway lines. Police said the suspect, who has been named as 27-year-old Akayed Ullah, sustained injuries including burns and wounds on his body related to setting off a bomb. Four others who were nearby at the time of the explosion sustained minor injuries.

Ullah was transported to Bellevue Hospital and remains in police custody. There were no specific or credible threats against New York City, officials said. 

You will see a greater presence of police personnel throughout the city. There are no other specific and credible threats against NYC at this time. #NYPDprotecting

Police said the bomb was "improvised" and "low-tech" and strapped to the suspect's body using Velcro and zip ties. It was based on the makeup of a pipe bomb, said NYPD Commissioner James O'Neill.

Both New York Gov. Andrew Cuomo and New York Mayor Bill De Blasio reiterated that New York is a target by many. Cuomo said in a press briefing on Monday that an attack on the subway system is "in many ways one of our worst nightmares."

This incident is being investigated as a terror attack. 

Let's be clear - this was an attempted terrorist attack. Thank God the perpetrator did not achieve his ultimate goals. Our first responders were there quickly and the only injuries we know of right now are minor.

— Bill de Blasio (@NYCMayor) December 11, 2017

We are a target because we prove a society of many faiths and many backgrounds can work - we show democracy can work. But we are the most resilient place on earth. We've proved it time and time again.

The NYPD will secure all transit hubs and major sites in this city. You'll see additional officers out in force. When you see something, say something. Speak up because you could be saving lives.

Ullah is said to have come to the U.S. on a F-4 visa from Bangladesh about seven years ago and had been living in Brooklyn, according to a report from the Associated Press citing unnamed sources. The suspect reportedly made the bomb in his basement and was inspired by the Islamic State, though he apparently had no contact with the group and is believed to have acted alone.

According to a report from CNN, a law enforcement source said Ullah told investigators he carried out the attack because of recent Israeli actions in Gaza.

CNN also reported that one law enforcement official with direct knowledge of the investigation said that in conversations with authorities, Ullah pledged allegiance to ISIS. CNN also reported Ullah held a Taxi & Limousine Commission license from March 2012 to March 2015, after which the license was not renewed.

The explosion took place in a subway tunnel connecting 42nd Street and 8th Avenue with 42nd Street and 7th Avenue. The Port Authority station is the busiest in New York.
