A pipe bomb strapped to a man went off in the New York City subway near Times Square on Monday, injuring the suspect and another person at the height of the morning rush hour, law enforcement officials said.
President Donald Trump used the attack to call for tougher U.S. immigration rules, saying the current "lax" policy "allows far too many risky, inadequately vetted people to access our country". Police spoke with Ullah's family in the borough's Flatlands section, CBS New York's Marcia Kramer reported.
Commuters underground near 40th Street and 8th Avenue began to flee after a loud, muffled sound was heard in the Port Authority subway station.
Ullah set off a low-tech explosive described by several media as a pipe bomb. "It was two distinct explosions seconds from each other".
The incident occurred less than two months after an Uzbek immigrant killed eight people by speeding a rental truck down a New York City bike path, in an attack for which Islamic State claimed responsibility.
The incident prompted the closure of segments of New York's transit system and officials are urging people to stay vigilant and report any suspicious activity.
Alicja Wlodkowski, 51, said that she had been in a restaurant inside the Port Authority when she suddenly saw a crowd of people running.More news: Hot Tickers: Kinder Morgan, Inc. (KMI), ImmunoGen, Inc. (IMGN)

"A woman fell, and nobody even stopped to help her because it was so insane", she said.

Former New York City Police Commissioner Bill Bratton reportedly said in an appearance on MSNBC Monday morning that the bombing suspect is believed to have been acting in the name of ISIS. On a typical weekday, about 220,000 passengers arrive or depart on more than 7,000 buses.
White House Press Secretary Sarah Sanders has tweeted that President Trump has been briefed on the explosion.
On the West Coast, the Los Angeles County Metropolitan Transportation authority asked law enforcement for heightened security along bus and rail lines as a precaution.
