“An improvised explosive device in a backpack detonated near the Elizabeth train station early Monday as authorities were using a bomb robot to examine the item, officials said.
The blast occurred around 12:40 a.m. near Morris Avenue and Julian Place. The explosion was not a controlled blast, but happened unintentionally as the robot was cutting the device, according to Mayor Christian Bollwage. No one was injured in the blast, Bollwage said.
Authorities found five devices inside a single backpack near the train station, including one that was detonated. After the explosion, press and bystanders were moved back because the four other explosive devices inside of the backpack were still believed to be live, Bollwage said.”
