A powerful explosion injured 29 people on Saturday evening in a crowded part of Manhattan, New York, and an unexploded device made using a pressure cooker similar to the one used by the Boston bombers in 2013 was discovered from the same area.
Authorities called the explosion “an intentional act” but based on preliminary investigations ruled out any links to terrorism. They also would not say if they suspected the two explosives were planted by the same person or people.
There were two other incidents that raised the prospects of terrorism the same day: A pipe bomb explosion in New Jersey and a stabbing spree in Minnesota claimed by the Islamic State.
Nobody was injured in the New Jersey blast, which was defined as “clearly an act of terrorism” by the state’s governor Chris Christie.
