The U.S. Department of Justice has announced new execution protocols, adding firing squads, electrocution, and gas asphyxiation to the methods used for federal executions. This move follows difficulties in obtaining drugs for lethal injections and fulfills former President Trump's initiative to revive the death penalty.

The Justice Department announced a series of actions on Friday aimed at restoring and expanding the use of the federal death penalty, including new execution methods and efforts to speed up capital cases.

US authorities announced reviving methods of federal execution, including bringing back the firing squad and the electric chair.
