A grieving dad set off two grenades at the trial of his son’s alleged killers in Ukraine on Thursday — killing himself and injuring several other people, according to reports.

The explosions rocked the courthouse in Nikopol, in the eastern Dnipropetrovsk region, and wounded at least seven people, the Sun reported, citing the Kyiv Post.

Three defendants were among the wounded, according to police.

“Today, on November 30, at 11:20, in the Nikopol court, during a hearing of the case on murder, the father of a victim pulled out two grenades and blew them up,” police said in a statement.

“The man died on the spot after the explosion. Three defendants, two convoy officers, a court employee and a civilian were injured. All victims were taken to the hospital.”

Images from the scene showed the blood-splattered walls inside the debris-strewn courtroom, where a door was left hanging off its hinges and windows were shattered, the UK’s Express reported.
