Surveillance video captured the explosion Saturday night that left at least 29 people injured.
The video was shot across the street from the blast. Authorities say the blast was clearly intentional but they aren’t calling it terrorism, at least not yet.
A second device was found 4 blocks away — a pressure cooker with wires and a cellphone attached in a garment bag. It did not detonate.
