Suspicious devices explodes near New Jersey station
A suspicious device found near a New Jersey railway station exploded as a bomb squad was attempting to disarm it with a robot, BBC News reports, citing officials.
It was one of up to five devices found in backpack inside a rubbish bin near the station in Elizabeth, according to the city's mayor. No-one was hurt, according to BBC News.
The discovery came after three attacks at the weekend - bombs in New York and New Jersey, and stabbings in Minnesota.
The explosion in New York's Chelsea area injured 29 people.
In Elizabeth, New Jersey, police detonated a device on Monday following concerns it was a live bomb.
"That was not a controlled explosion," said Mayor Christian Bollwage, adding that the blast happened as a robot examining a device cut a wire.
The bag containing a multiple devices was picked out of a bin by two men who thought it could contain something of value.
"They started to examine the backpack is when they found the wires and the pipes and they dropped the backpack, walked around the corner, went in to police headquarters and notified us right away," he said.
In New York City, the FBI said it had stopped a "vehicle of interest" in Brooklyn on Sunday but made no arrests.
