Three attacks in 12 hours.
An explosion in Seaside Park, New Jersey, on Saturday morning.
An explosion in Manhattan’s Chelsea neighbourhood on Saturday evening, and a second device discovered nearby.
A stabbing attack in a shopping mall in St Cloud, Minnesota, on Saturday evening.
And then up to five devices found in the same bag in Elizabeth, New Jersey, on Sunday evening.
