The Trump administration said on Friday that it would allow firing squads and readopt lethal injection as part of a broader push to revive the death penalty.

The US Department of Justice (DOJ) has directed federal prisons to expand the range of methods used for executions to include firing squads, gas asphyxiation and electrocution.

Acting Attorney General Todd Blanche says firing squads and the return of single-drug lethal injections with pentobarbital are part of a bigger push to ramp up capital punishment.
