Fourth of July holiday weekend marked by at least 17 mass shootings, data shows

At least 17 mass shootings were recorded across the country over the Fourth of July holiday weekend, including a string of deadly incidents that left as many as 18 people dead, data published by the Gun Violence Archive showed.

The shootings were recorded between Friday evening and into the early hours of Wednesday morning, according to the archive, a nonprofit that tracks gun violence in the U.S. and which defines a mass shooting as a single incident in which at least four people, other than the shooter, are shot.

At least 18 people were killed in the string of shootings, with at least 102 others injured, the archive said in a tweet.
