In Germany, eight people were killed and dozens more injured Thursday evening as a gunman opened fire on a Jehovah’s Witnesses congregation in the city of Hamburg. Authorities say the shooter, who fatally turned the gun on himself after the massacre, was a former member of the group. This is the fourth known mass shooting in Germany since 2020. Here in the United States, the Gun Violence Archive has reported 105 mass shootings so far in 2023.
