New York has been rocked by news of an explosion, believed to be a terror attack, at its main Manhattan bus terminal, which prompted a mass panic and stampede, according to reports.
A male suspect has now been named as Akayed Ullah, 27, who was injured when a low tech device strapped to his body blew up in an underpass, officials say.
The man is believed to have acted alone.
Earlier, the New York Police Department confirmed it was responding to reports of an explosion at 42nd Street and 8th Avenue.
One news source ABC News quoted police sources as saying that it was a possible pipe bomb, which went off in a passageway underground.
The Port Authority is the largest bus terminal in the US and serves more than 65mln people per year.
As yet, it is not known who is responsible for the blast.
There are no immediate reports of injuries ...
