The event happened on Monday just before 8:30 PM local time (1:30 AM BST on Tuesday), according to local news reports. The attack’s timing—the night before Independence Day—further exacerbated the community’s shock and grief.

One day before, a horrific shooting had occurred in Baltimore, Maryland, right before this awful incident. In that episode, a shooting rampage at a yearly community event resulted in the deaths of two people and the injury of a startling 28 people, many of whom were children. Police in Baltimore are aggressively looking for several persons who are thought to be behind the attack.
