Violence against media workers

The year before, 17 journalist and media workers were killed in Afghanistan, when a total of 121 cases of violence against journalists and media workers were reported.
During an attack in April 2018, nine journalists who rushed to the scene of a suicide bombing in Kabul were killed when a second suicide bomber who waited for first responders and others to appear on the scene ignited his explosives. A 10th journalist was killed the same day, shot in eastern Khost province.
