A terrorist attack on the Port Authority bus terminal in Midtown, New York City, New York occurred Monday, December 4. Akayed Ullah, 27 years old, entered the terminal and set off a homemade pipe bomb, injuring five people, Cable News Network reports.

“Officials said the suspect… pledged allegiance to ISIS and said he acted in response to Israeli actions in Gaza,” CNN reports.

Israel and Palestine have been warring over land and religious ideals since 1948. More recently, Israel cut off Palestine from trade and resources by closing the borders and issuing a naval blockade, CNN reports.

A large part of the fighting has been over the claim to Jerusalem, a city sacred to Jews, Christians, and Muslims.

“The situation in the region has become increasingly heated since US President Donald Trump announced last week the United States recognizes Jerusalem as the capital of Israel and will eventually move its embassy to the holy city,” CNN reports.

Since then, protests in Gaza and Palestine have increased due to outrage at Trump’s stance, CNN reports.

While five people were treated for minor injuries, nobody was killed in the attack. This is the most recent attack in New York City since eight people were killed by a man driving a truck into bikers Nov. 1, also an attack with motivations regarding ISIS.

“Today four courageous Port Authority police officers risked their lives confronting an armed terrorist to protect others from harm,” Paul Nunziato, Port Authority Police Benevolent Association President said in a statement posted on Twitter. “Police Officers Jack Collins, Anthony Manfredini, Drew Preston and Sean Gallagher entered a smoke and debris filled subway passageway, struggled with the suspect and denied him the ability to cause further chaos and destruction.

“I am so thankful there was no loss of life and I could not be prouder of our Port Authority police officers, their actions and dedications to their sworn duty.”

At 7:20 a.m. on a Monday, many people were commuting to work and school via the subway, leaving many eyewitnesses.

“It was two distinct explosions seconds from each other,” Franciso Ramirez said to CNN. “As I was making my way toward the outside, I kept getting shoved by cops and there were cops at every entrance blocking and there was police and SWAT everywhere.

“It was scary. It was just a lot of chaos but I didn’t see any injuries.”
