New Yorkers faced a commuting nightmare this morning after ISIS-inspired terrorist Akayed Ullah blew up a low-tech explosive at the Port Authority bus and train terminal in Manhattan.

Luckily, the device -- which was attached to his body with Velcro and zip ties -- just partially exploded, and Ullah was the only person seriously injured. The 27-year old also had an unexploded pipe bomb on his person.

He's being interrogated by the authorities at Bellevue Hospital, where he's being treated for serious burns and cuts to his abdomen and hands.

Ullah is Bangladeshi national who has been living in the U.S. for seven years. He told the investigators that he did the bombing because "they've been bombing in my country."

50 Cent, whose office is down the street from the Port Authority, had a message for Ullah and any other potential terrorist.

"What the fuck is going on, my office is right there. 👀Take that bullshit down the block man smh 🤦‍♂️," 50 says, under a photo of the scene.
