New York Governor Andrew Cuomo has officially classified the devices that were set off in the city over the weekend as acts of terrorism, although no suspect or motive has yet been identified.
Two explosions occurred in the city over the weekend, with one causing no casualties and the second injuring 29 people.
Both devices were shrapnel filled pressure cooker bombs similar to the ones used during the Boston marathon bombing in 2013.
A third device was found by law enforcement before it went off, and was detonated in a controlled explosion.
Speaking to reporters, the Governor labelled the acts terrorism after some initial official reluctance to do so, although at the moment no body has come forward to claim credit. Investigations continue into the incident.
New York Mayor Mayor Bill de Blasio said: “Was it a political motivation? A personal motivation? We do not know.”
“We know there was a bombing. We know it’s a very serious incident. But we have a lot more work to do to be able to say what kind of motivation was behind this.
“All possible theories of what’s happened here and how it connects will be looked at but we have no specific evidence at this point in time.”
